Summary: Nodes don't always know that the cluster has kicked them out

Initial Comment:
I have a 4 node failover cluster.  I dropped node 1 into the 
debugger to perform a failover to node 2.  Node 4 hit a breakpoint 
which I didn't get to in time.  I continued node 4 and it output 
"nm_nodedown_daemon: Node 1 went down" and just sat there.  
The cluster ended up consisting of nodes 2 and 3, but node 4 never 
realized that it had been declared down.

In a production environment if a node is declared down by the 
cluster it is in, if it is still alive it should reboot itself.  This way it 
might be able to rejoin the cluster.

According to John this is a problem in the node monitoring 
algorithm.
