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