/* Remove calls to XFlush by defining XFlush to an empty replacement.
Calls to XFlush should be unnecessary because the X output buffer
is flushed automatically as needed by calls to XPending,
XNextEvent, or XWindowEvent according to the XFlush man page.
XTread_socket calls XPending. Removing XFlush improves
performance. */
