The Python folks don't know about withlist or Mailman specific methods,
so this is the appropriate place.

The problem is just what it says. The script is trying to lock the list
(mlist.Lock()), and the list is already locked (withlist -l option).
There are several ways around this, but the easiest is to just remove
-l from the withlist command.
