[pypy-dev] update on CPython coroutine

[Stephan Diehl]

Hi all,

after my (unsuccessful:-) attempt to place CPython runnable coroutines 
into py.magic (they might end up there just after the next release, 
we'll see), they live now in
http://codespeak.net/svn/user/stephan/hacks/coroutine/coroutine.py
In order to use them, on must place that file into the python path.
I've fixed a couple of things, Armin pointed out to me. I'd be happy to 
get some feedback.

Background: the pypy.lib.stackless_new implementation relies only on 
coroutines as a special requirement.
If one had coroutines that were running on CPython, one could run have 
the stackless interface on CPython as well (minus the pickling, of course).
It turned out that the coroutine interface is so similar to the greenlet 
one, that just a few lines of code are enough to provide the coroutine 
interface to greenlets.

Have a nice weekend

Stephan
