Although I haven't been able to achieve the pace that I originally wanted, I have been able to work on my multi-core Python idea little-by-little. Most notably, some of the blockers have been resolved at the recent PyCon sprints and I'm ready to move onto the next step: exposing multiple interpreters via a stdlib module.

Initially I just want to expose basic support via 3 successive changes. Below I've listed the corresponding (chained) PRs, along with what they add. Note that the 2 proposed modules take some cues from the threading module, but don't try to be any sort of replacement. Threading and subinterpreters are two different features that are used together rather than as alternatives to one another.

At the very least I'd like to move forward with the _interpreters module sooner rather than later. Doing so will facilitate more extensive testing of subinterpreters, in preparation for further use of them in the multi-core Python project. We can iterate from there, but I'd at least like to get the basic functionality landed early. Any objections to (or feedback about) the low-level _interpreters module as described? Likewise for the high-level interpreters module?

Discussion on any expanded functionality for the modules or on the broader topic of the multi-core project are both welcome, but please start other threads for those topics.
