[Twisted-web] Guard, LastPage Memory Leak?

I'm running a guarded app. Memory is not released on logout.
I read carefully nevow.guard and I'm debugging widely with
pdb and gc.
I encountered the following problem. It sounds really strange.
I discovered, using pdb and gc inside logoutPortal(), that
visited pages remain alive.
So, I created a WastingMemPage(rand.Page) class that, on __init__,
allocates ton of mem (no external referrer, memroy is allocate
inside the instance only). I will return it initializing each
def locateChild(self, ctx, segs):
return WastingMemPage(), segs
Now, each time I hit one of this WastingMemPage, memory
usage grows. When I logout ( portalLogout() ), memory is
* Is a rend.Page() not deleted once rendered?
* Altough the previous question, why pages remain
linked from something after portalLogout()?
What's happening? Am I making some mistake? Is there some
limit on portalLogout()?
py 2.5/2.4. Nevow 0.9.31.
