The *XSync()* function flushes the output buffer and then waits until
all requests have been received and processed by the X server. Any
errors generated must be handled by the error handler. For each protocol
error received by Xlib, *XSync()* calls the client application's error
handling routine (see "Using the Default Error Handlers
<http://tronche.com/gui/x/xlib/event-handling/protocol-errors/default-handlers.html>").
Any events generated by the server are enqueued into the library's event
queue.
The part about flushing the output buffer would tend to disagree...
