   Agreed.  Looking at its exit point I see two local variables being discarded   
   *and* a near RET.  In other words, it uses more, not less stack that the   
   simpler solution ...

   I have not looked too hard at the packetdrivers API to see if I could find   
   one,  but what about the last stack adjustment XCHG-ing the saved register   
   with the stacks intended value ?   
      
   I'll have to look into that, if only to see if it would work (can't imagine   
   it will be pretty).

   Clever: using an IRET to grab the flags and jump to the intended target.   
   Dont' think I would ever thought about doing it that way.   
      
   Thanks for the code /help.
