def end_request(self):
        """Undo :meth:`start_request`. If :meth:`end_request` is called as many
        times as :meth:`start_request`, the request is over and this thread's
        connection returns to the pool. Extra calls to :meth:`end_request` have
        no effect.

        Ending a request allows the :class:`~socket.socket` that has
        been reserved for this thread by :meth:`start_request` to be returned to
        the pool. Other threads will then be able to re-use that
        :class:`~socket.socket`. If your application uses many threads, or has
        long-running threads that infrequently perform MongoDB operations, then
        judicious use of this method can lead to performance gains. Care should
        be taken, however, to make sure that :meth:`end_request` is not called
        in the middle of a sequence of operations in which ordering is
        important. This could lead to unexpected results.
