Create a file in the locking directory:
   qrunner.lock.moya.trilug.org.22845

That should lock out qrunner from accessing the lists while you do your
sync. Be sure to delete the lock file when your sync is done.

Mailman's logs are a rich resource for information on users
subscriptions and unsubscriptions.  You could easily setup some scripts
to populate the changes from one installation onto another one.

Of course that doesn't handle list configuration changes, but a simple
config_list dump could easily propagate those settings.
