example.

* Unfortunately, all of the above documentation holds with the X11
* backend only. With the Win32 backend, GDK and GTK+ calls should not
* be attempted from multiple threads at all. Combining the GDK lock
* with other locks such as the Python global interpreter lock can be
* complicated.
*
* For these reason, the threading support has been deprecated in
* GTK+ 3.6. Instead of calling GTK+ directly from multiple threads,
* it is recommended to use g_idle_add(), g_main_context_invoke()
* and similar functions to make these calls from the main thread
* instead. The main thread is the thread which has called gtk_init()
* and is running the GTK+ mainloop.
