The last issue of the newsletter went out yesterday without
any problems, so I think setting QRUNNER_LOCK_LIFETIME did
the trick. The subscriber base on this list is about 27,000
so Mailman can handle the list size. I think it was my
original tweaks pushing for performance that caused this whole
mess to erupt.
