    Ensure that _XReadEvents always leaves an event in the queue on return
    
    XNextEvent assumes that the event queue will be non-empty on return from
    _XReadEvents, but with multiple event readers running, the previous change
    could leave the queue empty on return from process_responses. Re-invoke
    process_responses until the queue is non-empty.
