Welll the easiest thing to do is to see if import _continuation fails. And if 
it does fail, try to import 
greenlets. Also keep the old greenlet code. This is very much the way the 
previous stackless.py
worked.

I would be happy to work with other folks that are interested in the 
stackless.py module. I have a 
patchy knowledge of PyPy but a decent knowledge of stackless.py and stackless. 
Let me study continuations and the existing stackless.py module. In
 this fashion, I can make every hint I ask count.

As discussed on IRC, I think an approach that would work is fork stackless.py 
in two. One branch would be conventional. That that,  it would track C 
basedStackless but incorporate stuff like continuelets and bug fixes and more 
conservative features.

The other branch would be experimental. Wilder stuff would be done there.

Cheers,
Andrew
