573
574 After a ConfigureWindow, according to ICCCM section 4.1.5, we
575 should recieve a ConfigureNotify, either a real or synthetic
576 one. This indicates that the configure has been "completed".
577 However, some WMs such as several versions of Metacity fails to
578 send synthetic events. See bug
579 http://bugzilla.gnome.org/show_bug.cgi?id=322840. We need to use a
580 timeout to avoid a hang. Tk uses the same approach. */
