menu bug solved?

lisp/sawfish/wm/menus.jl


popup-menu function in the sawfish WM process, does this:

	      (ungrab-pointer)
	      (ungrab-keyboard)
	      (sync-server)
...
              (format menu-process "(popup-menu %s %S %S)\n"
		      ;; write out the menu spec in one chunk to
		      ;; avoid large numbers of system calls :-[
		      (format nil "%S" (mapcar menu-preprocessor spec))
		      (x-server-timestamp) offset)



sync-server does:     XFlush (dpy);                      


i think, that XFlush is not enough. XSync is needed, b/c X server could first
serve the requests of the sawfish-menu client, and deny it the grab.

ps:
what does (x-server-timestamp) do is a different issue....
