Seems doubtful (though I'm not an expert).

This suggests that only one microthread is ever really being run at
any given time. I would venture a guess that the lack of "true"
parallel-ness is probably a design decision deeply ingrained into
Stackless and is not changeable. You'd probably have to change to
multiprocessing or threads.
