   You are correct.  The window size does put an upper bound on the example   
   that I gave.  But the DoS is still a problem.  Especially if I'm able to   
   establish multiple connections and send up to the window size.   
      
   However you go about it, you don't want to indefinitely hold onto all   
   packets.
