Your checklist for this pull request
Second round of refactoring - move session management out of the database object (to make atomicity easier).
Beware of the dragons, this code has a long history of concurrency bugs. In the previous version, there was an implicit commit all the time... I'm not sure there are no places where i should call .commit() directly, but so far it works in my tests.
