This was recently reported by Mike Boev. It appeared when I added the
smfMainStart() routine in LibSnert 1.36. It has been fixed in 1.41, to
be released sometime soon.

This I cannot answer. How BDB handles its writes I do not know. It
should happen when the milter is stopped or at predetermined intervals.
I've not asked Keith about it.

The grey-listing is a secondary technique only used when the call-back
technique results in an indeterminant answer. This of course assumes
your setting of MxAcceptsAllAction is one of the four grey-list
variants. Also consider, has the domain past a previous challenge
successfully and therefore been cached only to spam afterwards.
Grey-listing cannot stop a spammer that plays by the rules.
I would need some example domains to test against and/or log extracts in
order to determine what is doing wrong, since its unclear to me why it
would by-pass otherwise. If its a cache related problem, then you might
have to go back a far bit in time to figure it out.
