The code has already been delegated to whomever wants it since no
other core developer maintains the code. And that is my worry; the
bsddb code base is owned by either no one or a single person since no
one else wants to deal with it (and I tried; I helped with the initial
transition to 3.0). For as long as I have been a core developer, if
you asked me what module or package caused the greatest amount of
grief for the core developers, I would have always answered bsddb.
I appreciate you want to maintain the code, Jesus, but that still
makes you the single point of failure for the code. If you decide you
don't want to deal with it, or are on vacation when the code breaks
just before a release, it is quite possible we are screwed. The Python
code base is not owned or maintained by a single individual, and yet
bsddb has been handled by a single person for as long as I can
Short of new code from _multiprocessing, everything else has been
ported to 3.0 throughout the development process without nearly as

Assuming you even want to use Berkeley DB. And not all of us are on
Linux. This is one of those situations where an argument tends to
break out over what types of things should be included in the stdlib.
I think bsddb is heavier than what we should include. But that's my

Well, _build_class__ is a built-in, so something is not running under
a proper environment.
