There is a point if it can actually sync the filesystems.  A totally
graceful shutdown would be ideal, but if this is failing already there
needs to be a way to do halt(8) or reboot(8) so at least the file systems
are synced.

I have seen the "no more processes" message too many times in recent
weeks to not want something cleaner than the reset switch.  And if you
do something stupid like add 'softdeps' to /usr in /etc/fstab, you could
use something that can call sync(2) or just reboot(2) directly.
