First of all, +1 but didn't look so indepth this time either. Enough to me that
it's pretty well tested already. :-)

A bit off topic, but have you ever tried DB_TXN_NOSYNC ? Should add
considerable performance, and the "risks" are more than fine for this use..
You could try adding it in this line in BDB.pm:
my $flags = DB_INIT_LOCK|DB_INIT_LOG|DB_INIT_MPOOL|DB_INIT_TXN;
In fact, I think the flags should be user configurable to some degree..
