And why are there factory functions in threading.py and not classes?
I'm not sure, but it looks like a poor man's way of discouraging
You usually use factory functions if you only define an API that
can then be implemented in many ways.
With a class hierarchy you are always bound to one implementation
and moving from Python to C or providing different specifically
optimized implementations can become cumbersome.
ElementTree is another example that uses factory functions.
