If you need a large amount of concurrency, you might look at Jython
with threads.  Jython threads well.

If you don't intend to do more than a few hundred concurrent things,
you might just go with CPython and multiprocessing.

Fortunately, the interfaces are similar, so you can try one and switch
to another later without huge issues.  The main difference is that
multiprocessing doesn't show variable changes to other processes,
while multithreading (more often) does.
