{
{   The purpose of this request is to advise the OS that access
{ to a portion of memory is finished (for a while).  This request
{ is intended to allow a task to assist memory manager in managing
{ the working set.  If the system load is high, memory manager
{ may ignore this request.
{
{   For each page totally or partially contained within the portion of the
{ segment defined by <pointer> to <pointer> + <length>, memory
{ manager does the following:
{ -If the page is in the JWS and has not been modified,
{  the page is removed from the JWS and placed in the 'available'
{  page queue.
{ -If the page is in the JWS and has been modified, the page
{  is removed from the JWS and placed in the 'available-modified'
{  queue.
{
{   It should be noted that the above algorithm is subject to change
{ as a result of system performance studies.
