Says tye:

How does a child wait for a parent to exit? (use flock as an IPC mechanism)

Another related technique:

    # in the child:
    while (whatever...) {
      do_some_work();
      if (getppid() == 1) {
        print "my parent is dead!";
            clean_up();
        exit;
      }
    }
