Presumably the stack poisoning has somewhat of an impact on boot times
and coreboot users generally care about that? 64KiB stack with
MAX_CPUS = 16 is 1MiB of memory just for stack and it's poisoning.
It's definitely not dire, but just something to think about. I'm not
sure what the expectations are for boot time from existing users.
