Hi Folks:

I have been reading a few papers on lock-free data structures (and reading some 
posts on Golang Nuts). I was thinking about writing new a version of 
stackless.py with Go's select. However I would try to use lock free data 
structures and techniques in the channel implementation. My questions:

1) Would I be using the pypy-stm branch? (because there is no GIL)
2) Would I write some of this in RPython? (I am assuming yes)
3) Do I have access to low-level atomic operations (I don't think the 
high-level transaction module gives me access)?
4) Does stackless features work with pypy-stm (I haven't yet been successful in 
compiling a pypy-stm branch so I can't test this out myself).

Cheers,
Andrew
