No. That's what got us into this mess in the first place.
3.5.0 and 3.5.1 *already* changed to the new behavior, and it resulted
in the situation where CPython blocked forever at startup in these
certain edge cases. os.urandom() has been around for more than a
decade, we can't unilaterally change its semantics now. os.urandom() in
3.5 has to go back to how it behaved on Linux in 3.4. And if I were
release manager for 3.6, I'd say "it has to stay that way in 3.6 too".
However, Guido's already said "don't add os.getrandom() in 3.5", so the
debate is somewhat irrelevant.
