> Currently we clear a server from the deadserver set once we finish processing 
> it's shutdown.  However, certain circumstances (network partitions, race 
> conditions) could lead to the RS not doing a check-in until after the 
> shutdown has been processed.  As-is, this RS will now be let back in to the 
> cluster rather than rejected with YouAreDeadException.
> We should hang on to the dead servers so we always reject them.
> One concern is that the set will grow indefinitely.  One recommendation by 
> stack is to use SoftReferences.
