    Hi!

    You can find an implementation of stackgap from OpenBSD at http://
    people.freebsd.org/~ssouhlal/testing/stackgap-20050527.diff

    You can control the range of the random stack gap with the
    kern.stackgap_random sysctl. A value of 0 disables it. Otherwise, it
    has to be a power of 2 and not too large. The default value is 64K.

    I've only had the chance to test this on i386. Could anyone test it
    on other architectures as well?

    Any comments/objections?
