Subject: keep the databases separate

otherwise, to keep all the dbs in the same file we need to call
mdb_env_set_maxdbs before mdb_env_open ... and even then the docs say:

"Currently a moderate number of slots are cheap but a huge number gets
 expensive: 7-120 words per transaction, and every mdb_dbi_open() does
 a linear search of the opened slots."

Ugh. that and the mem mapping probably gets screwed oever .. whatever.

this way hawd works again :)
