OK, thanks for the info. I'm not sure if I've ever really update
the GMain docs for GLib-2.0; certainly I haven't updated the overview.

g_[timeout,idle]_add_[full] are just convenience functions.

  GSource *source =  g_time_source_new (100);

  g_source_set_callback (source, function, data, notify);
