But page walking can do good even on\nother OSes, because it guarantees that villain thread hits\nthe guard page before it can make damage to innocent one...\n\nChange-Id: Ie1e278eb5982f26e596783b3d7820a71295688ec\nReviewed-on: https://boringssl-review.googlesource.com/13768\nCommit-Queue: Adam Langley \u003cagl@google.com\u003e\nReviewed-by: David Benjamin \u003cdavidben@google.com\u003e\n",
