@r.david.murray, yes, this avoids list creation, but is still quite slow.

To create 1mb of data, you can compare the following:

    python -m timeit -s 'from os import urandom' 'print(len(urandom(1000000)))'

    python -m timeit -s 'from random import randint' 'print(len(bytes(randint(0, 255) for i in range(1000000))))'

On my system `os.urandom` is 0.04sec, using randint takes 2.24sec (approx 50x slower).
