Fixed bug when recving on an "empty" socket.

        decoded, do it and pass result to :meth:`dispatch` method.

        '''

        try:

            buf = self._sock.recv(RpcConnection.RECV_BUF_SIZE)

        except socket.error as err:

            if err.errno == 11:

                # Errno 11 -> retry again

                logging.warning('Non critical error while reading a socket:'

                                ' %r', err)

                return

        if not buf:

            # Empty buffer = closed socket.

            raise socket.error()

        self._inbound_buffer.push(buf)
