     *  The main use of XSync is by the update command, which alternates
     *  between running an event loop to process all events without waiting and
     *  calling XSync on all displays until no events are left.  On X11 the
     *  call to XSync might cause the window manager to generate more events
     *  which would then get processed. Apparently this process stabilizes on
     *  X11, leaving the window manager in a state where all events have been
     *  generated and no additional events can be genereated by updating widgets.
     *
     *  It is not clear what the Aqua port should do when XSync is called, but
     *  currently the best option seems to be to do nothing.  (See ticket
     *  [da5f2266df].)
