I disagree, it's just an issue of a comment in the C code. The Python documentation doesn't guarantee that os.urandom() is cryptographic.

Use ssl.RAND_bytes(), added to Python 3.3, if you need cryptographic random numbers.

By the way, VMS is no more supported in Python 3.3, see the PEP 11:

    Name:             VMS
    Unsupported in:   Python 3.3
    Code removed in:  Python 3.4
