This reminds me that message passing to the main program thread in GTK+ is normally done using g_idle_add() (which is thread safe) and there was a proposal to make the Glib::SignalIdle::connect() wrapper thread safe with a new Glib::SignalIdle::connect_once() function. I don't know if Daniel has got anywhere with that http://mail.gnome.org/archives/gtkmm-list/2007-January/msg00051.html You can however use the unwrapped g_idle_add() for passing your callbacks to the thread in which the default programme GMainContext is running, if you want.
