{    The purpose of this request is to create an exact duplicate of the current
{ task.  Both the requesting task and and forked task are identical and resume
{ execution at the same point.  This request is intended for use by the UNIX

{       PMP$FORK_TASK (U_AREA_SOURCE_SEGMENT, U_AREA_DESTINATION_SEGMENT,
{             CHILD_TASK, STATUS);
{
{ U_AREA_SOURCE_SEGMENT: (input)  This is the segment number (in the parent
{       task) of the u-area the parent has created for the child task.
{
{ U_AREA_DESTINATION_SEGMENT: (input)  This is the desired segment number to
{       which the u-area created by the parent task is placed in the child
{       task.
{
{ CHILD_TASK: (output)  This is false if the task is the caller of
{       pmp$fork_task.  This is true if the task is the result of a fork.
{
{ STATUS: (output)  This is the resulting status of the request.  A zero (0)
{       result indicates that the fork attempt was successful.  A non-zero
{       result indicates that the request failed.
