see answers below. I'm debugging with pdb and gc. Maybe I
discovered something, but the debug process is slow.

Ok. on Page.afterRender() I put `self` on a list. After 5 hits
to this page, I'm checking where these pages are referred.
I have this for the first page on the list:
<myfile.pages.MyPage object at 0x4069eeac>})
Do this tell you something?

Yes. I will build a minimal framework.
