That sounds like a real performance win, but even though the databases
ought to be compatible, apparently the API has changed from 4.0
enough that SASL 2 won't even compile. Didn't try Cyrus because
of this, since mixing DB versions has always been a disaster before.

Any hopes for updates to current stable SASL2 and Cyrus 2.1
to accommodate BDB 4.1?
