      When we issue a _killoperation to cancel a hedged read, we do not know if the remote server has already processed the original read and registered its clientOperationKey. As a result, the _killOperation can be processed before the original read and "miss" its intended operation.

       

      Acceptance Criteria: Tests should ensure that we make the best effort to kill outstanding hedged reads but not require that we do so.
