   Hummm... Not necessarily? Think of a server loop. It can halt if it gets   
   a certain command, but ideally, it wants to be up running "forever", in   
   a sense...   
      
   Think of an infinite IFS fractal loop that ideally wants to plot   
   forever. Its process runs for as long as it can. The hardware can die   
   out, but that does not mean the code halted, just its "vehicle", so to   
   speak...
