Having slept on it, I suspect you're right. I worry about some
BUG_ON() that really relies on the killing behavior, but if it takes a
"real" fault later, that is when it gets killed. And on the whole,
we've had lots of problems with the killing behavior over the years,
so we should just try switching BUG_ON() over to non-fatal. It's
unlikely to be worse than what we have now, as exemplified by this
event.
