{
{   This request  is  called  in a parent task when one of its child tasks has
{ terminated.  It frees any Block stack frames created by  or  for  the  child
{ task  that  have not already been freed.  It then erases the parent's record
{ of the child task.
{   Also, if the child task is the "current job synchronous task" (the task to
{ be sent interactive "break" signals), then the parent is made to  take  over
{ that role.
