Yeah, except I think only one of those would actually work
(the "permanent objects" idea). The "thread-local refcount"
idea seems to have at least one fatal flaw.

I'm now more interested in the IBM "Recycler" idea that
was mentioned. If I get a spare moment, I might have a
go at implementing a "Repycler" by means of suitable
redefinitions of Py_INCREF and Py_DECREF.
