		Your current Emacs is compiled with GTK+. There is a long-standing
		bug in GTK+ that prevents Emacs from recovering from X disconnects:
		<https://bugzilla.gnome.org/show_bug.cgi?id=85715>
		If you run Emacs as a daemon, then it is strongly recommended that
		you compile it with the Motif or the Lucid toolkit instead, i.e.
		with USE="motif -athena -gtk" or USE="athena -gtk -motif".
