    Description

      Currently, the status reporting thread is sent an interrupt and immediately after that TaskUmbilicalProtocol.done() is invoked. A better thing to do is to wait for the thread to die before invoking done() otherwise it is possible that a status message just makes it through and then the Task is put in RUNNING state at the TaskTracker. This results in inconsistency about the runstate of a task at the TaskTracker's end.
