[PATCH] Stackgap

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?
