		Your current Emacs is compiled with GTK+. There is a long-standing bug
		in GTK+ that prevents Emacs from recovering from X disconnects:
		<https://gitlab.gnome.org/GNOME/gtk/-/issues/221> and
		<https://gitlab.gnome.org/GNOME/gtk/-/issues/2315>.
		If you run Emacs as a daemon, then it is strongly recommended that you
		compile it with the Lucid or the Motif toolkit instead, i.e. with
		USE="athena Xaw3d -gtk -motif" or USE="motif -gtk -athena -Xaw3d".
