semantics of os.urandom() in 3.5.2rc1 are indistinguishable from reading
from /dev/urandom directly, except it may not need to use a file handle.

Which is a contract change. Someone testing in E.g. a chroot could have a
different device on /dev/urandom, and now they will need to intercept
syscalls for the same effect. Personally I think this is fine, but assuming
i see Barry's point correctly, it is indeed but the same as it was.
