Worst case scenario is if the system does come up enough for the hardware watchdog to get kicked in a timely manner, but nothing else works.

The watchdog needs to be the last initialized bit of code on the system.

Even so, determining when a partition is "bad" is hard.

Of course. The hardware watchdog is just one of many things that should be taken into account. I picked it as an example, specifically because a lot of people don't know such a thing exists on many embedded systems.
