Heh, I had considered dropping it entirely even from the generic code, since I don't remember seeing that ever trigger, but PeterZ convinced me otherwise.
For the s390 side I really wanted to keep things minimal since I (obviously) didn't even built-test it, so..
I'm perfectly happy with s390 people adding it later, of course.
