> 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.
