hmm. I'm not a big fan of OpenBSD's randomization code. I'm not
rabidly against the patch but it is a bit hackish. It seems to me
that somthing similar could be implemented simply by having the RTLD
or LIBC code mmap() a randomly sized dead segment, and not have to
build anything into the kernel.
Wouldn't that result in 2x the syscalls for calling mmap()?(isn't this
expensive?) Or do I not understand what you mean?
