[Xcb] How to wake up the GUI thread in XCB?

[Bart Massey]

If your code is threaded anyway, it's probably best to just have a separate
thread for event handling. XCB is fully thread-safe, so you can mix calls
to xcb_wait_for_event() in the event-handling thread with GUI drawing calls
in another thread. This was actually the intent of the XCB architecture.
