That's not true. The pip bootstrapping uses a custom action, and
we already have one that is similar (compile to pyc), although that
isn't run by default.

My guess is that it might try verifying signatures, and somehow tries
to obtain the CA certificates (although it's puzzling that it would get
them from akamai - perhaps MS is hosting the CA bundle there).
