    Andrew,

    I looked at this few days ago. I am not sure how we end up having
    multiple pages (especially,
    why we end up having buffers with bh_size > pagesize) ? Do you know why ?

    Easiest fix would be to fix submit_bh() to deal with multiple vecs -
    which is vetoed by
    Jens and I agree with him :(

    Thanks,
    Badari
