According to [1], we don't need to worry about GDK's global lock since we don't call gdk_threads_init() or gdk_threads_set_lock_functions(). The GDK threads API is being aggressively deprecated by GTK+ developers so let's just abandon it entirely. I've never really understood when you're supposed to use it or not use it anyway, so it's good to be rid of this confusion.
