It's not always run - it's opt-out for the Windows and Mac OS X installers
and not invoked implicitly at all if installing from source. The bootstrap
also needs to be available for use by "venv".

There's also the significant fact that python-dev still has a blanket ban
on externally maintained standard library modules (for good reasons) and
the clear separation between the bootstrap module and pip itself is what is
allowing this proposal to adhere to that guideline.

Cheers,
Nick.
