[Stackless] Why can't I use nanosleep() to suspend the execution of a stackless tasklet?

Right now living in the "future" requires a lot of legwork in the present. Outside reviewing my  STM book and getting static-stm-barrier branch to build on my tiny computers, I have to come up with working hypothesis about how Stackless works on top of STM. I believe we can take clues from concurrency/STM in Haskell. An immediate concern is that transaction.py assumes the units of execution are threads not tasklets. I am guessing to get around this will entails me having a far better understanding of how continuelets and stacklets (this is what PyPy uses for microthreading) interact with OS threads.

Cheers,
Andrew
