exec "shutdown now" needs time.
cold can keep data in DRAM for a long time

sb. break into your house and cold your shutdowning computer. your data in memory will not cleaned up so quickly.

if you have a full-disk encryption. the key will find in mem-data for high risk in such a condition.

and, i'm not sure if truecrypt did some security-related cleanup here.

so. just call systrigger for poweroff as quickly as possible.

use poweroff, but reboot. for cmos will not fill the full memory. so we can get last boot data from memory if we use reboot.
