Hm, I wouldn't have drawn the picture that way.  As I understand it,
the garbage collection changes to the C Python that we use have not
compromised its reference count driven behavior at all.

You're just looking at the other Python there, Jython.  Its object
lifetime policy is Java's, and that doesn't support timely finalization.
There's your spanner.
