Thanks for taking the time to explain!  It makes sense, but I'd need to
educate myself better about how Pypy can be used along our current
Python version library (as in, does it require its own .pyc files? Does
it dismiss CPython's produced ones?  Can we not point it to consume our
existing Python libraries (it's different sys.path suggest differently),
etc.)
