> HAVE_GETRANDOM_SYSCALL seems to be a compile-time library check, not a runtime check. I compiled and run on Linux 3.15.5, and os.getrandom() exists but raises ENOSYS: Oh, I'm surprised the configure sees getrandom() as available. But well ok, the error can occur if you compile Python on a more recent kernel than the running kernel. I fixed the unit test: skip getrandom() tests if getrandom() fails with ENOSYS. Do you think that it's worth to document this case?
