I understand. I understand the PyPy team is busy. And I have privately
received some useful feedback.

Well if I can get select() to work, I would be more than happy to 
maintain and expand stackless.py. stackless.py is too cool and
important to be just left sleeping.

Meanwhile, I have written much simplified tests. I get the same errors.
Given that problems revolve around context switches in schedule() and
the probably the main tasklet, I believe there are modules other than stackless.py that I need to modify. I also need to understand some of 
the terminology - for instance, nesting_level. Does that refer to frames. Or tasklets or coroutines? Again, I think there is something very simple at the bottom of all this - I am just a newbie.
