Raymond, this is not an experiment, but the beginning of a sustained effort to improve locality during execution, to make more effective use of CPU cache lines. Rather than discuss the details of this change one PR at a time, I will close this issue for now, and open a discussion on python-dev.

stage: patch review -> resolved
