While I can't speak for the OP, isn't it the case that the threadlets in 
Stackless (sorry, don't know what they are really called) are true 
threads in the sense of being able to switch contexts no matter how far 
down in a set of nested calls they might be?  And that NanoThreads are 
simply generators, which means you can switch contexts only at the top 
level, with a yield statement?

I don't know what the OP wants, but I could imagine that would be a 
pretty fundamental difference (if I'm right about Stackless).
