No, GObject have a fency notification queue. This is used to allow calling
g_object_notify () without notifying twice, but also to not notify twice if one
call:

  g_object_set (object, "prop", val, "prop", val, NULL);

We even use this feature from within GStreamer (see calls to
g_object_notify_freeze/g_object_notify_thaw).
