Notably, if you prelink things this turns off some of the randomization (stacks are randomized, but the mmap() area can't be, because the whole point of prelink is to fix the load addresses of libraries and eliminate the need for them to be relocated).

But this is no real problem, as long as you use the -R option to prelink, which does a static randomization (but the addresses are still random, so an attacker must still brute-force things).
