Where do the N loops come from? I have read Christian's "Stackless Python" paper (http://www.python.org/workshops/2000-01/proceedings/papers/tismers/stackless.htm) and slowly but surely I do more stuff with the C Stackless code base. That said, I haven't found any particularly good papers on how the Python interpreter itself is architected. Maybe I should look at how the greenlet package works. Again, I would be happy to help but I am not quite sure where to start so at least I can ask intelligent questions in the pypy IRC.
