I suggest to reject this proposal because of a deterioration in security.

If somebody is going to implement uuid based on the random module that somebody
must take care of fork. Currently the PRGN in random isn't reseeded during
fork(). This would lead to 100% collisions. The tempfile module contains a
workaround for the issue.

Ok, let's reject the issue then.

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.
Agreed. urandom() is supposed to

You could help this along by both running Lib.test.test_uuid with your patch
applied and reporting that it passes.
Raymond, I added you because this is about changing random functions.
Side note: This code in test_uuid.test_uuid4()

New submission from Matt Chaput m...@whoosh.ca:
Currently the 'uuid' module uses os.urandom (in the absence of a system UUID
generation function) to generate random UUIDs in the uuid.uudi4() function.
This patch changes the implementation of uuid4() to use random.getrandbits() as
the source
