Just running a very big test of this thing, and it seems you're *very*
right. By the looks of it, Mailman loads in all of the delivery_status
and digest information before it even sends the first mail.

Given that, the performance penalty of all those connect/cursor/etc.
calls is horrendous, and I need to rethink a little.

On the good side, though, I *think* I've got the get/setBounceInfo
functions working now, but I've had to import the _BounceInfo class in
order to create the appropriate object instance to make it work. Don't
know if that's going to be a problem...

Current Versionisms:

MysqlMemberships.py: 1.24
MysqlMemberships.py.README: 1.15
MysqlMemberships.py.TODO: 1.6

Pondering whether to send a message to mailman-users about this thing,
or not. I don't like the prospect of my server getting slashdotted
though :(
