Which code? gvobject.py? Anyhoo, it's useless...

Well, it turns out it's not immediate. Someone told me that Python 2.4
does a collect every 700 deallocations (a value than can be tweaked
with gc.set_threshold, I think). And it makes sense: I see my
destroyed objects finally being freed when I do other stuff like
opening a new window. But it's still not fast enough in certain cases.

I finally found out that it was not a Python problem... I needed to
put a few g_object_unref's in my override file. Kinda like a sink().

That's what I was trying to do with my wrapped barebone class and the
simple script but
it was too simple to be useful :)
Anyhoo, I made a lot of progress today, thanks all!
