Restarting one side has no effect on the other.

In this particular case under discussion, restarts are caused when:

	We received a packet from a node we thought was dead

	The sending node has not restarted since we last heard from them

Then, heartbeat will force a local restart.


If A thought B was dead, generally B would also think A to be dead.  If this 
is true, and each side sends packets to the other, then both sides will restart.


It isn't about restarting causing restarts, it's about receiving these 
packets from "dead nodes" (seeing a ghost if you will ;-)), that causes 
restarts.
