[issue12986] Using getrandbits() in uuid.uuid4() is faster and more readable

        uuids = {uuid.uuid4() for i in range(1000)}

However, I'm not sure of the legitimacy of replacement suitable for cryptographic use `os.urandom` on fast pseudo-random `random.getrandbits`. Especially for applications that need to generate a lot of uuids.
