    And I might add, undoing the entropy to result in the descending page
    list (but that is the forth time I've said this).

    I ran heavy sequential load overnight and continued to have this
    characteristic when taking snapshots of command SG lists. The average SG
    element size statistically was 4168 bytes.

    In 2.4 at least it shows no sign of degenerating in that way, something
    in the VM is undoing the entropy
