Brian Somers 6f8e9f0a8a 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.
