Comment #6 on issue 256 by [email protected]: [patch] decrease resident memory usage.
http://code.google.com/p/address-sanitizer/issues/detail?id=256

My patch catches every single unpoising.
Exactly. mmaps are expensive.

memsetting 4k of memory is also expensive.

Unless I see a proof that the proposed approach does not slowdown the common use-case,

I'll provide the requested benchmark as soon as possible (but I have professional constraint and cannot spend too much time on it for now). That said, you should seriously consider adding a reference benchmark in the repository if you expect contributions, because you can hardly ask for a benchmark to every single person who propose a patch.
