When contributing code to Python all work remains copyright the original 
author. The combined work is copyright *everyone*. The PSF has a license 
to distribute it, which is all that is important.

How you meaningfully exercise your ownership over chunks of code is left 
for the reader to determine...

(i.e. copyright and ownership are legal terms that don't necessarily 
mean anything *practical* in these situations.)
