Thanks for reporting, I think the change I just checked into CVS
should fix this (admin.py was calling MailList.SetUserOption() without
the keyword argument "save_list=0", causing the list to be Save()d at
least

  admin_user_chunksize * len(("hide", "nomail", "ack", "notmetoo", "plain"))

times(!) every time the list's Membership Management page was
visited).

The bigger a admin_user_chunksize you're using, the bigger this win
will be :)
