Looking at his code, I think it's clear he wants a separate

    dummy_threading.py

and nothing fancier than that.  The idiomatic use would be as shown, where a
user who knows what they're doing can import dummy_threading (if desired)
and *name* it threading locally themself (if desired).  No existing code
could break, except for users who already have a file named
dummy_threading.py on their PYTHONPATH somewhere after the std library.
