The processes dont seem to be failing. New list mail is delivered fine,
but what's 'stuck' in the queue doesn't leave until a restart which
effectively does a queue run.

I found this information from the faq on python.org. Our traffic
pattern is very bursty. Lists are small, maybe 25 users per list, but
when traffic comes in, it's alot at the same time (monitoring mails).
