> It was the single test that failed the hbase-2 nightlies in #440 at the 
> hadoop2 stage.
> The failure manifests as a timeout. It actually has an interesting cause 
> calling into question some of the clauses in 
> UnassignProcedure#remoteCallFailed.
> We are running a disabletable concurrent with a shutdown. pid=309 is the 
> disable. pid=311 is the interesting one. The below is a little hard to read 
> -- the exception 'message' is the the current procedure as a String... hard 
> to parse, fixing -- but we are trying to unassign as part of a the 
> disabletable. Our RPC fails because the server we are trying to rpc too is 
> currently being processed as crashed (pid=308 is a servercrashprocedure for 
> this server). As part of the processing of the failed RPC we will expire the 
> server -- if we can't RPC to it, it must be gone. The current procedure is 
> then suspended until it gets woken up by the servercrashprocedure triggered 
> by the expire.... only in this case we are shutting down so the expire is 
> ignored... The current procedure is left in its suspend state. This prevents 
> the Master going down. So we time out.
