Implemented thread merging

It can happen that thread messages are not delivered in order, which
means we will have to merge threads once all messages are available.

+
+Hi,
+
+during the KUserFeedback BoF at Akademy there was quite some interest in 
+collecting telemetry data in KDE applications. But before actually 
+implementing that we agreed to define the rules under which we would want to 
+do that. I've tried to put the input we collected during Akademy into proper 
+wording below. What do you think? Did I miss anything?
+
+Regards,
+Volker
+
+
+# Telemetry Policy Draft
+
+Application telemetry data can be a valuable tool for tailoring our products 
+to the needs of our users. The following rules define how KDE collects and 
+uses such application telemetry data. As privacy is of utmost importance to 
+us, the general rule of thumb is to err on the side of caution here. Privacy 
+always trumps any need for telemetry data, no matter how legitimate.
+
+These rules apply to all products released by KDE.
+
+## Transparency
+
+We provide detailed information about the data that is going to be shared, in 
+a way that:
+- is easy to understand
+- is precise and complete
+- is available locally without network connectivity
+
+Any changes or additions to the telemetry functionality of an application will 
+be highlighted in the corresponding release announcement.
+
+## Control
+
+We give the user full control over what data they want to share with KDE. In 
+particular:
+- application telemetry is always opt-in, that is off by default
+- application telemetry settings can be changed at any time, and are provided 
+as prominent in the application interface as other application settings
+- applications honor system-wide telemetry settings where they exist (global 
+"kill switch")
+- we provide detailed documentation about how to control the application 
+telemetry system
+
+In order to ensure control over the data after it has been shared with KDE, 
+applications will only transmit this data to KDE servers, that is servers 
+under the full control of the KDE sysadmin team.
+
+We will provide a designated contact point for users who have concerns about 
+the data they have shared with KDE. While we are willing to delete data a user 
+no longer wants to have shared, it should be understood that the below rules 
+are designed to make identification of data of a specific user impossible, and 
+thus a deletion request impractical.
+
+## Anonymity
+
+We do not transmit data that could be used to identify a specific user. In 
+particular:
+- we will not use any unique device, installation or user id
+- data is stripped of any unnecessary detail and downsampled appropriately 
+before sharing to avoid fingerprinting
+- network addresses (which are exposed inevitably as part of the data 
+transmission) are not stored together with the telemetry data, and must only 
+be stored or used to the extend necessary for abuse counter-measures
+
+## Minimalism
+
+We only track the bare minimum of data necessary to answer specific questions, 
+we do not collect data preemptively or for exploratory research. In 
+particular, this means:
+- collected data  must have a clear purpose
+- data is downsampled to the maximum extend possible at the source
+- relevant correlations between individual bits of data should be computed at 
+the source whenever possible
+- data collection is stopped once corresponding question has been answered
+
+## Privacy
+
+We will never transmit anything containing user content, or even just hints at 
+possible user content such as e.g. file names, URLs, etc.
+
+We will only ever track:
+- system information that are specific to the installation/environment, but 
+independent of how the application/machine/installation is actually used
+- statistical usage data of an installation/application
+
+## Compliance
+
+KDE only releases products capable of acquiring telemetry data if compliance 
+with these rules has been established by a public review on [kde-core-devel|
+kde-community]@kde.org from at least two reviewers. The review has to be 
+repeated for every release if changes have been made to how/what data is 
+collected.
+
+Received data is regularly reviewed for violations of these rules, in 
+particular for data that is prone to fingerprinting. Should such violations be 
+found, the affected data will be deleted, and data recording will be suspended 
+until compliance with these rules has been established again. In order to 
+enable reviewing of the data, every KDE contributor with a developer account 
+will have access to all telemetry data gathered by any KDE product.

+Hi, 
+
+thank you very much for this work, sounds great! 
+
+Only point I have: maybe make sure that the opt-in / default settings are not 
+only mandatory for application developers, but also for packagers / 
+distributions. 
+
+Some distributions have rather questionable views on privacy and by default 
+sent information to third parties, so I would feel much more safe if they 
+weren't allowed (in theory) to flick the switch in their package by default to 
+"on" either.
+
+Kind regards, 
+
+Christian

+
+Hi all, Mozilla has done a lot of work on telemetry, and we might be
+able to use some of their findings. On this page:
+https://wiki.mozilla.org/Firefox/Data_Collection they break down the
+data they might possibly collect into four buckets - technical (such
+as crashes), user interaction, web activity, and sensitive (personal
+data).
+
+This bit might be relevant to our discussion: "Categories 1 & 2
+(Technical & Interaction data)
+Pre-Release & Release: Data may default on, provided the data is
+exclusively in these categories (it cannot be in any other category).
+In Release, an opt-out must be available for most types of Technical
+and Interaction data. "
+
+I think the entire page might be enlightening to this discussion. I
+believe our analysis of needs should be more fine-grained, and that
+some parts of what we need can be "default on" especially for
+pre-release testing. For releases, we can provide an opt-out.
+
+Other more sensitive data will need to be opt-in. I think it's a
+mistake to treat all the data we might want all in the same way.

+This again brings up opt-out, which so far doesn't seem to have a chance for 
+consensus. Can we defer this to when we have some more experience with the 
+opt-in approach and how much participation we get with that? Or are people 
+feeling this would too strongly limit what they are allowed to do in their 
+applications? 
+

+I've pointed alexey at this thread, but there's a huge language barrier:
+he basically communicates through google translate. I've made it a firm

+Hi Valorie,
+Even if opt-out for some data is legally and even morally fine, it does not 
+align with the values we communicate to our users:
+Unlike Mozilla's Mission, our Vision mentions privacy explicitly, and we're 
+striving to make privacy our USP.
+
+Therefore I agree with others who replied in this thread: We should respect 
+privacy unnecessarily much rather than too little.
+
+In the end, of course, it's a matter of how we present this opt-in. If it's an 
+option buried in some settings dialog, we might as well not do it at all.
+
+If we, however - like Firefox does -, pfominently present that choice to users 
+the first time they run one of our applications or desktop environment and try 
+to make clear why that data collection is important for us, I don't see why we 
+could not convince a relevant number of users to opt in.
+Sure, we'll get less data than with an opt-out scheme, but let's try it out 
+first before we go for the option that carries a significant PR risk.
+
+> Other more sensitive data will need to be opt-in. I think it's a

+
+Content (web activity for Mozilla) and personal information should not be opt-
+anything but not collected at all.
+
+Cheers,
+Thomas
