Alexey Suslikov (he's working on the OpenBSD wine port and has helped me get it
working) asked me to post this:
"From http://www.openbsd.org/security.html

New Technologies

As we audit source code, we often invent new ways of solving problems.
Sometimes these ideas have been used before in some random application
written somewhere, but perhaps not taken to the degree that we do.

   * strlcpy() and strlcat()
   * Memory protection purify
         o W^X
         o .rodata segment
         o Guard pages
         o Randomized malloc()
         o Randomized mmap()
         o atexit() and stdio protection
   * Privilege separation
   * Privilege revocation
   * Chroot jailing
   * New uids
   * ProPolice
   * ... and others

Tijl Coosemans (on 16023) refers to SELinux as for randomized mmap
and arguing for ELF pre-loader for wine while Alexandre Julliard objects.

What I'm asking for, is to provide a links to above security.html page and
simply tell about randomized mmap is not only for SELinux but also for
OpenBSD.

Alexey"
