It is inviolable. We don't include it in default kernel as panic for
performance reasons, but it doesn't mean it can happen. If it happens it
is unexpected condition that is most likely not handled at all.

We use plain panic(9) in places that should not but can eventually
happen for reasons out of our control. For example if you are running in
VM and someone is corruption your disk image as you run. We do want to
detect it as quickly as possible.
