Yes, in Python 2.x, dbm.py is very specifically an interface to the
Unix dbm library (see e.g. man dbm_open).  At the level of C, the gdbm
interface is some kind of extension of that.  It's not related to
bsddb, which has a very different interface.

I think either is fine (or even not sharing at all if it turns out to
be too much of a mess in practice).

A bientôt,
