Given that SDBM is *way* faster than DBM, and is even faster than SQL, we should
use SDBM by default.
The only reason not to at the moment is that it screws up existing installs. It
would be nice to have some way of automatically converting or something, but I'm
not sure how this can be done.

Suggest we hold on this for the moment. SDBM has not undergone any
serious testing in a production environment.

It might be the fastest because it's doing everything wrong.

I think we should probably do this for 3.2.0. I've been using SDBM_File on my
scanners for several months now without noticing any bad side effects

actually, I heard someone mentioning problems with reading data from an SDBM db
while another process is writing; this works in DB_File and is pretty critical
for SA, so perhaps we should hold off on SDBM use until that's investigated.

fwiw, DB_File has problems with reads during a write, though it could be
specific to reading the data that's being changed. See bug 3563.
