Erm, don't we have this part already?  Oh, you mean on top of
_CPython_, rather than on top of py.py on top of CPython.  I guess
this would help testing...

This would be good.  Samuele pointed out some more stackless examples
at:

    http://members.verizon.net/olsongt/stackless/why_stackless.html

It would be nice to add these to the test suite (some of the examples
use pygame, so those need to be changed).

We've just had a quick IRC discussion, and we decided that it would be
really nice if you could work on the pre-emptive scheduling mentioned
in the description of WP07; this will require adding a hook to the
interpreter than is called every few hundred bytecodes, but other than
that should mostly be implementable at app level (and the design
stolen from stackless CPython, I guess).
