I don't think he needs all 15 cores for that, assuming the Python processing is the more expensive. 

But it would avoid having the GIL change hands on each asynch i/o event.

It would also keep the thread that runs the interpreter in cache, if it never goes to sleep. That way objects associated with the interpreter would not be swapped in and out, but kept in cache.
