+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.
