Started a patch a long time ago, but this needs a lot of changes, so the
best would be a rewrite of the DBM-code. (IMHO) *SIGH*

I'm using tdb with since ages, it's stable, and you don't have to care
about different db-libs/headers. It also provides a feaure named
chanlocking,
that allows a finer grained locking. And as far as I know it allows
multiple writers.
