On-disk key -> value dictionary.  In every use of bsddb that I've seen
(or done myself), that's been the extent of it's use.  That's what I
*was* offering.  But it seems that everyone has had experience with
bsddb on a far deeper level (beyond dictionary + cursor access), and
would find (like you) absolutely no use in an on-disk dictionary with
a sqlite backend (which hasn't had the same maintenance issues as
bsddb), which is why I withdrew the offer.
