Subject: If we've got a full output buffer queue and cannot send anything for
 two mintues (see ``set choked'' and ``show bundle''), nuke the ip, mp and
 link level buffer queues.

This should fix problems where ``ppp -auto'' seems to stop
responding after failing to connect to the peer a few times.
