Mail was delivered after two months

Under some conditions, I've seen Cyrus deliver hang.  This is  
probably a bug in the various Cyrus delivery & LMTP programs, tho  
I've not gone looking.  Ideally, every step of delivery, from the MTA  
through final delivery would have timeouts to detect this sorts of  
hanging bugs.  When both the MTA and Cyrus fails to detect a hang,  
mail can be held for a long time.

To prevent this particular problem, I would recommend running  
something that looks for processes that ought to be move or less  
transient taking a long time.  It ought to be harmless to kill those  
hung processes, and once they are dead and locks will be released and  
the MTA can retry.
