There are many solutions to handling the scaling of Python on multicore processors, only one of which is killing the GIL. Another is Greg Ewing's ideas offered in the "Ideas towards GIL removal" thread in the python-ideas list.

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.
