queue not preprocessing

[Daniluk, Cris]

I've noticed a couple times that qmail will stop preprocessing messages and
the queue will have say a thousand messages, but 900 of them will not yet be
preprocessed. Giving an ALRM to qmail-send does not seem to make a
difference. Is there anything that would trigger this? It's certainly got
enough resources of every kind at its disposal...
