    Bug #9154: Always process an event for _XReadEvents, even if an error occurs
    
    Previously, process_responses (in the wait_for_first_event case called
    from _XReadEvents) considered any return from xcb_wait_for_event
    sufficient to think it had processed an event. If xcb_wait_for_event
    returned an error, and no more events occurred before process_responses
    called xcb_poll_for_event, process_responses would try to return with
    dpy->head NULL, and would fail an assertion for the _XReadEvents
    postcondition. Now, process_responses continues using xcb_wait_for_event
    until it gets an event.
