Instead of encumbering the factory functions which implement the old API with an optional dbenv argument, I think if people want to provide their own environment it's reasonable to expect them to use the new bsddb3 API. All we should do with the old API is make it work in a multi-threaded environment if possible. Skip

Agreed, that sounds like a good option.

In my previous email I had forgotten about the DB_PRIVATE flag to DBEnv objects; that prevents them from writing extra DBEnv files to the filesystem for use when multi-process access is not needed.

I just committed the small change needed to bsddb/init.py for it to use a DBEnv allowing multithreaded access. The original hammer.py from bug 775414 has been running for 15 minutes without problems on my alpha with BerkeleyDB 4.1.25.
