Yes, the final node cannot have parents or children, because it's run at 
the end of the run, no matter how far through the DAG you get.  So, for 
example, if a bunch of nodes fail and only half of the DAG finishes, the 
final node still gets run before DAGMan leaves the queue.  If the final 
node had any specific parent, that would violate these semantics.
