Brandon Williams reopened CASSANDRA-1108:
-----------------------------------------


Turns out this isn't good enough.  We've shutdown the Gossiper's timer on node A, but node B will call gossipToUnreachableEndpoints, choose A, and A will still reply.

> For when a node is failing but not yet so badly that it can't participate in gossip (e.g. hard disk failing but not dead yet) we should give operators the power to forcibly mark a node as dead.
> I think we'd need to add an extra flag in gossip to say "this deadness is operator-imposed" or the next heartbeat will flip it back to live.
