auto-pruning mailman messages held for approval

[Seth Vidal]

Hey,
  in /var/lib/mailman/data/ there are an ass-tonne of messages held in 
various approval queues.

This morning there were a total of 21778 messages waiting for various 
lists. Some of them are NOT young.

Since they are just files that live in that dir - how would folks feel 
about setting a 2-month limit? If a message is not 
approved/discarded/rejected/etc by the mailing list admin w/i 2months then 
tmpwatch it away?

it, ultimately, makes mailman run better.
