Note that if you want to integrate your own callbacks with GTK+
GUI callbacks in the same thread (like repaint events), you need to do
1... you can only have one running contex per thread. And in fact, what
gtk_main() looks like is basically:

 gtk_threads_leave();
 g_main_loop_run();
 gtk_threads_enter();

So it's very much the "normal" way things work.
