Multiprocessing broken on Windows since 1.1

Traceback (most recent call last):
  File "<string>", line 1, in <module>

This is probably an upstream bug but there might be a workaround: http://bugs.python.org/issue10845

Could be this one: pypa/pip#1891

So #173 caused this? Are we getting any benefits from wheel that make it worth the bugginess?

Thanks
