Perhaps I also ought to add that if, in the light of this, you are
thinking of using g_idle_add_full() and are thinking of passing a slot
as the data argument of that function, make sure it represents either a
static method, or a non-static method of a class not deriving from
sigc::trackable, as sigc::trackable is not thread safe.
