Good news (kinda) - another list on that server just started to slow
down, and this time, it is a very unimportant and small list (472
members, 466 of them have mail delivery enabled), so I can take all
the time in the world to try and debug this issue.

Well, unfortunately, this doesn't reproduce the problem. Neither does
stopping Mailman and copying every single file to another server.
However, restarting Mailman (something I don't do very often) does
_not_ solve the problem, either.

Do you think I can drop Barry a PM off-list and ask him for further
advice if he doesn't read this? I'm really interested in debugging
this, and as I said, this time I really don't care about the list
delivery being slow.
