[pygtk] centralized multiple instances of a pygtk app

If your application truly needs to be cross platform (the following
holds on windows), don't ever touch gtk.gdk.threads_init/threads_enter
/threads_leave. You'll need to rely on gobject.threads_init and only
allow the main thread to touch your ui (via gobject.idle_add for example).
See http://git.gnome.org/browse/pygtk/tree/examples/threading/gtk_threading.py
for a working example.

No ideas here atm, sorry...
