        * gdk/x11/gdkgeometry-x11.c (gdk_window_queue): Keep
        the length of the anti-expose queue finite, by if
        it gets too long, first doing a XSync() and checking
	the event queue, and if that doesn't work, simply
        discarding all anti-expose items in the queue.

	* gdk/x11/gdkdnd-x11.c (gdk_window_cache_filter): Fix ordering
