I tried applying the upstream fix for 3.5:

https://hg.python.org/cpython/rev/337461574c90

However, the monster patch does not apply.

patching file Python/random.c
Hunk #2 succeeded at 39 (offset -1 lines).
Hunk #3 succeeded at 54 (offset -1 lines).
Hunk #4 succeeded at 65 (offset -1 lines).
Hunk #5 FAILED at 77.
Hunk #6 FAILED at 143.
Hunk #7 FAILED at 162.
Hunk #8 FAILED at 203.
Hunk #9 FAILED at 236.
Hunk #10 succeeded at 350 (offset -27 lines).
Hunk #11 succeeded at 374 (offset -27 lines).
Hunk #12 succeeded at 506 (offset -27 lines).
Hunk #13 succeeded at 525 (offset -27 lines).

Will try to dig out the other patches from 3.5 branch that this depends
on tomorrow. I can't reproduce the getentropy() failure either,
apparently it only occurs on kernels < 3.17.
