One thing to look at. When Mailman doesn't shut down, which of the qrunners
is still running? All of them, or only XMLRPCRunner?

If it's all of them, then there may be a problem propagating signals from the
master to the child qrunners. If it's just the XMLRPCRunner, then your
scenario could indeed be happening. Note that if any of the child qrunners
don't exit, the master won't exit either since it's waiting on the pids of all
its children.
