        This method is used only to run _Query/_GetMore operations from
        cursors.
        Can raise ConnectionFailure, OperationFailure, etc.

        :Parameters:
          - `operation`: A _Query or _GetMore object.
          - `set_secondary_okay`: Pass to operation.get_message.
          - `all_credentials`: dict, maps auth source to MongoCredential.
          - `listeners`: Instance of _EventListeners or None.
          - `unpack_res`: A callable that decodes the wire protocol response.
