Here's my first patch. This correctly implements __getattribute__ and
__getattr__ in the single class case. FWIW I also have a mercurial tree
if it'd be better to pull from it than apply patches.

I'm working on making subclasses behave correctly, I've got test cases
written up showing where things fail, but no solutions to that written
yet. The slot_tp_getattro stuff Stefan mentioned is useful though.
