    The vm_object structure is now somewhat smaller due to the removal     of most of the swap-pager-specific fields, the removal of the id,     and the removal of paging_offset.

    A new inline, vm_object_pip_wakeupn() has been added to subtract an
    arbitrary number n from the paging_in_progress count and then wakeup
    waiters as necessary.  n may be 0, resulting in a 'flash'.
