    then later logs out from the ssh session, the server connection is
    closed, unintentionally SEGVing the Emacs process.  I think we should

Yes, would someone please do so?

However, once the multi-tty branch handles this just as well as
the current version, this issue is no longer an obstacle to merging in
the multi-tty branch.

We alredy have a workaround in place (gtkutil.c):

  /* GTK 2.2-2.8 has a bug that makes gdk_display_close crash (bug
     http://bugzilla.gnome.org/show_bug.cgi?id=85715).  This way
     we can continue running, but there will be memory leaks.  */

  g_object_run_dispose (G_OBJECT (gdpy));
  /* This seems to be fixed in GTK 2.10. */
  gdk_display_close (gdpy);

But I don't have all versions of Gtk+ in place, so if anybody can confirm that this does not work on some Gtk+ version, we can skip the g_object_run_dispose call also.
