    I'm going to try and do some clean up work on the iostat CPU results -
    the reason %user & %system are so low is (I think) because they also
    include a lot of 0% results from the tail of the runs (as the unmount is
    going on I think). I'm going to try and extract results for just the
    "meat" of the runs.
