Witness doesn't panic on LORs. These are all bigger violations for things
like doing sx_sunlock() on a exclusively locked sx lock. That is not safe and
is merely going to result in data corruption and other unpleasantness. This
sounds like a very bad idea. Did you talk about this anywhere (I have not
caught up on various lists yet, so apologies if this has been discussed.)
