postgrey seems to use proper locking and DB_RECOVERY, so it *should*
work.  But postgrey disables durable transactions:

    my $setflags = DB_TXN_NOSYNC;

On some file systems, this adversely impacts the consistency after
system crashes.  It would be interesting to know what happens if the
line is changed to:

    my $setflags = 0;

(BTW, the submitter isn't Cc:ed, is this correct?)
