44 Don't use getentropy() on Linux
46 Issue #29188: Support glibc 2.24 on Linux: don't use getentropy() function but
47 read from /dev/urandom to get random bytes, for example in os.urandom(). On
48 Linux, getentropy() is implemented which getrandom() is blocking mode, whereas
49 os.urandom() should not block.
