in a Gtk/Glib context, i have:


template<typename T> gint idle_delete (T *obj) { delete obj; return
FALSE; }
template<typename T> void delete_when_idle (T *obj) {
	Glib::signal_idle().connect (sigc::bind (sigc::ptr_fun
(idle_delete<T>), obj));
}

you would need some equivalent of Glib::signal_idle()
