Except that the delay is likely because the OutgoingRunner was
slugishly making its way through the "between 80 and 100 .pck files in
queue/out at this time", each of which is a separate message to be
delivered.

The question is why is OutgoingRunner so slow as to create such a
backlog or perhaps what happened to dump all these messages into the
queue at once.

Also, there could be an issue with the qfiles/out directory being
physically large even if it only contains a smaller nubmer of entries
now, although that should only affect storing new queue entries, not
retrieving them. See the post at
<http://mail.python.org/pipermail/mailman-users/2005-July/045667.html>
for more info on this and some other tips too.
