    Ah, as have I [1].. and they seem to have gotten about as far as I have,
    which means almost there but not quite [2] :-)

    The most interesting case is file maps and they simply ignored those.
    While I appreciate that from an academic pov, -- they can still write a
    paper on the other interesting bits -- I don't really like it from a
    practical point.
