How about fixing cyclic gc to deal with __del__ instead? That sounds
like an awful change to the semantics.
Hum? That's the purpose of the PEP 442 which is implemented in Python 3.4.
As I wrote, it's not enough to fix all issues.

I would not expect it to be cleared at least until go runs ... and reading
the ticket, it sounds like it is cleared then.
