Here's a good function header given the following:
I wrote the below code

    @functools.wraps(func)
    def decorator(*args):
        key = test_support.threading_setup()
        try:
            return func(*args)
        finally:
            test_support.threading_cleanup(*key)
    return decorator

What's a good function header?
