    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.
