If you always have more than one new message on each loop of the
scheduler, your system is not going to be able to catch up unless
you can make the scheduler loop more often.  ;-)

The problem is that it's fairly easy to create traffic which causes
the todo queue to grow faster than it can be processed.  At one point
a few years ago I had tweeked with building an SMTP system that could
handle injecting messages into a queue much faster than qmail, and I
had relative success.  Let me run that test again...  Nearly 400
3KB messages per second.  I really should find time to work on that
system again...
