> Somehow, people are running into a situation where nodes are adding themselves to the
persisted ring cache.  Since SS is initialized after the Gossiper and calls addSavedEndpoint
on it, which inits the nodes with a generation of zero, this ends up with nodes using a generation
of zero and thus never being marked as alive.
