* Triage and fix/skip all test failures
* Stop embedding expat strings
* Add a way to disable network tests. ATM they fail silently, so this isn't a big priority
* Look at importing distutils-sysconfig.diff from cpython, if it's needed.
* Forward patches to PyPy upstream:
  - pep3147-*
  - usr-prefix
  - compiler-flags
* Work out the details for module packages supporting pypy.
