def exit_status_ready(self):
return self.closed or self.status_event.is_set()<EOL>
Return true if the remote process has exited and returned an exit
status. You may use this to poll the process status if you don't
want to block in `recv_exit_status`. Note that the server may not
return an exit status in some cases (like bad servers).

:return:
    ``True`` if `recv_exit_status` will return immediately, else
    ``False``.
