My script for our nightly cycle follows.  I age off log files as I
do this.  This looks fairly simple, but there's some hidden learning,
e.g. it takes our LISTSERV 30 seconds to die sometimes, due to delays
in closing down all its delivery channels.  Also, sending a "STOP"
command is almost completely pointless, as it can take too long to get
through the queue to be useful.  (I had one sent at midnight-ish which
was acted upon at 2:08 AM, long after a kill-restart, once.)  On VM,
where interactive messages were taken out of order, STOP worked better.
(Listening, Eric? :-)  Of course, on VM, closing spooled console logs
and transferring them was nicer too.
