Sorry for the delay.
getrandom_nonblocking_v4.patch LGTM, but I made a major change: if getrandom() fails with EAGAIN, it now *always* fall back on reading /dev/urandom.
I also documented the change in os.urandom() documentation and in Misc/NEWS.
I pushed the fix to Python 3.5 and 3.6. Python 2.7 doesn't use getrandom() and so doesn't need the fix. I now consider that the bug is fixed.
If you consider that it's important enough to retry calling getrandom() each time os.urandom() is called, please open a new issue with a patch and elaborate your rationale :-)
----------
resolution: -> fixed
status: open -> closed
