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

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.
