Actually testing the ABI stability would be much harder - somehow
building an extension module against 3.2 with the limited API then
testing it against a freshly built 3.3. Perhaps we could manage
something like that by building against a system installation of
Python 3.2 on builders that have it available.

All in all, I think PEP 384 laid the foundations, but there's still
plenty of work to be done in the documentation and testing space (and
perhaps a few API additions) before the majority of extensions can
realistically switch to the stable ABI. A bit of "eating our own
dogfood" in the extension modules we ship may be a good place to start
(especially new ones that are added).

Cheers,
Nick.
