Review comment:
       I think you removed the outer condition. Let me copy my previous comment:
   
   I know `RemoteException` coming from `readStatus` is imp to us but we don't 
want to swallow IOException if `inStream.readInt()` throws one because 
`inStream.readInt()` is pre-requisite to know whether the status is 
`SaslStatus.SUCCESS`
   
   I am talking about what is happening within `readStatus(inStream)` call.
