Greenlets are unrelated to multithreading or multiprocessing.  They
are related to Stackless Python.

So far PyPy cannot even *have* a JIT together with Stackless Python
features like greenlets, but this is going to change soon; in this
next model, PyPy's JIT will not work across greenlets, but will
happily JIT every single greenlet individually.


A bientôt,

Armin.
