pystone is a very good benchmark for one thing: testing the "general speed" of the interpreter. Perhaps because it is so atypical, it's hard to do something that gives pystone a significant speed boost

I've been working with Damien to make sure the improvements are not pystone specific. We've run against my highly optimized matrix code, against pybench, and against another one of my programs which heavily exercises a broad range of python tools.

Overall, his improvements have helped across the board. I think his lastest and greatest should be accepted unless there is a maintainability hit. However, the core concept and code seems clean enough to me.

FWIW,
