I'm actually no longer convinced that it makes soo much sense to get
rid of the GIL. Python's data model is not made for free threading.
Have you had a look into http://www.parallelpython.com/ ?
Might be a starting point into threads with disjoint interpreters
and some locking just for data exchange.
