I'm vaguely familiar with those C# calls. When I have time, I'll download your
stacklesslib module. I'll also download a copy of C# (and maybe F#) so I can
compare. That said, I think that functionality exists because 1) C# does not
have lightweight threads 2) Microsoft has done extensive concurrency research
(i.e, look at the paper "Cooperative Task Management without Manual Stack
Management" and some of that knowledge is starting to get into their modules.

Have you thought about experimenting with PyPy's stackless.py module? I believe
under the hood, it has single shot continuations. You get the additional bonus
of JIT support.
Cheers,
