    Oh, no, I'm _much_ more nifty than that!

    Instead of being very clever, I have a very _stupid_ algorithm, one that
    has very hardcoded expectations of exactly what it will see. And if it
    doesn't see exactly that, it just fails early.

    I'd post the patch, but I really need to actually _test_ it first, and I
    haven't rebooted yet.
