Is this right? I thought we had decided that os.urandom should *not* fall back on getrandom on Linux?
We decided that os.urandom() should not *block* on Linux. Which it doesn't; we now strictly call getrandom(GRND_NONBLOCK), which will never block. getrandom() is better because it's a system call, instead of reading from a file. So it's much less messy.
If getrandom() wanted to block, instead it'll return EAGAIN, and we'll fail over to reading from /dev/urandom directly, just like we did in 3.4 and before.
It's all working as intended, //arry/
