Hi Johannes,

I think we were waiting on some review, but if that has stalled out,
let's go ahead and commit it.  Default off is fine for now.  It can be
improved as needed and then we at least have an ASLR story for the
checkbox users.

KASLR is less useful (grsecurity folks might say useless) — see
https://forums.grsecurity.net/viewtopic.php?f=7&t=3367 for some
discussion on it.

Best,
Conrad
