You're right that Oleg raised a concern about how mmap(MAP_GROWSDOWN) behaves, and is wondering about how to make it more sensible: but that's neither a vulnerability nor a regression - he agreed minor, to think about another time. He's also been fielding a concern from the CRIU people, we're hoping that's just something they need to fix at their end - ah, no, I see Oleg has just replied ahead of me, not digested yet, I'll look into that later...
