Is using Cython for anything in Modules/ really an option? In my limited 
experiments with it, I did like it.

But using it for Python standard library stuff doesn't look quite right 
to me:

- Option 1: distribute Cython with Python and integrate into build process
-- Ouch!

- Option 2: only distribute generated source files
-- developers still need to have Cython installed
-- you have to trust Cython; who will really review the generated code?
