Do you want to do an alternative patch Victor? Or point out all the specific bits of my patch you don’t like?

I haven’t really been keeping up to date with the getrandom() changes. Though I imagine even Python 3.6’s os.urandom() will still fall back to /dev/urandom (with potential entropy problem) on older Linux versions. Is the consensus that we want to warn about insecure results on Linux >= 3.17, but don’t want to warn about older Linux versions?
