Comment 7 for bug 651182

Hi all,
   and thanks a lot for your attention.
   The simple patch in attachment fix the problem, so it means
   the bug is inside
       /usr/lib/mailman/bin/mailmanctl
   not in init script
       /etc/init.d/mailman

   I suppose there's a wrong implementation of flag '-s':

       -s/--stale-lock-cleanup
        If mailmanctl finds an existing master lock, it will normally exit
        with an error message. With this option, mailmanctl will perform an
        extra level of checking. If a process matching the host/pid described
        in the lock file is running, mailmanctl will still exit, but if no
        matching process is found, mailmanctl will remove the apparently stale
        lock and make another attempt to claim the master lock.

Thanks a lot for your work,
Andrea
