How about unsubscribes? Changes of address? I would suggest that the
most reliable way is to put hooks in the Mailman/OldStyleMemberships.py
member adaptor routines addNewMember and removeMember. This will get
changes of address too because that is done by a remove and add.

Another is to create something that would parse the subscribe log and
get those list names that have entries with time stamps later than the
last run and do bin/list_members for those lists, and run it frequently
via cron. This has the advantage of not modifying Mailman, but has the
drawback that address changes aren't logged (unless you are running
<https://code.launchpad.net/~mailman-coders/mailman/2.2>), and there may
be log rotation issues to deal with.

If you have lots of excess resources, you could just run
bin/list_members for all lists at frequent intervals via cron. e.g.

for list in `/path/to/bin/list_lists --bare`; do
  /path/to/bin/list_members $list > /path/to/${list}_member_list
