Wow, it's by design:
" os.urandom(n)
Return a string of n random bytes suitable for cryptographic use."
``man urandom'':
"A read from the /dev/urandom device will not block waiting for more entropy. As a result, if there is
not sufficient entropy in the entropy pool, the returned values are theoretically vulnerable to a crypto-
graphic attack on the algorithms used by the driver."
