Hi again, Andrew,
I'm going to fix stackless.py on pypy.
Can you maybe try your version if it already behaves correctly
when run on PyPy? Or does it also build upon the slightly
wrong version?
thanks & cheers -- Chris

A note. The last time I looked, the version of the PyPy Stackless
module that took advantage of (single-shot) continuations. However unlike
the older version, it took out greenlet support. I rather liked the way
the code could execute over PyPy's coroutines or greenlets.
As a sidenote. Myself I have two broad versions of stackless.py. One
is in the Stackless repository that supports select(). I have a
variation where
I experiment with improving Pike's select algorithm - I think it is too
conservative.
The second version that I haven't released since there is even less
interest than
that the version with select, is my initial experiments with join
patterns. Since
in the literature, the join implementation (and channel implements)
also uses STM
and other lock-free techniques, I probably resume experimentation with
CPython-atomic
as well as improve the API.
Cheers,
Andrew
