We now build a separate APE binary for each test so they can run in parallel. We've got 148 tests running fast and stable so far.
These are the commits from https://github.com/ahgamut/cpython/tree/cosmo_py36 squashed for simplicity. Also included is the pyconfig.h used for compilation. The pyconfig.h has to be changed manually in case Cosmopolitan gets new features.
README.cosmo contains the necessary links.
