> With large clusters (> 500 nodes) and num_tokens > 255 we sometimes see a 
> node have trouble starting up.  CPU usage for one thread is pegged.
> We see this concurrent with Gossip flaps on the node trying to learn the ring 
> topology.  Other nodes on the ring, that are already at steady state do not 
> seem to suffer.  It is the node joining the large ring that has trouble.
