Randomizing heap placement makes heap exploits harder, but it
also breaks ancient binaries (including anything libc5 based).
This option changes the bootup default to heap randomization
disabled, and can be overriden runtime by setting
/proc/sys/kernel/randomize_va_space to 2.

On non-ancient distros (post-2000 ones) N is usually a safe choice.
