btw, i solved that particular problem in one of my kernels by adding a pause_on_oops_head and pause_on_oops_tail hack some time ago. (It properly and well deservedly died an entropic death.)
So the problem space is real, and our tools for it suck to a certain degree. Your generalization would certainly help.
