That's just a godawful solution.   The way Apple does it is better -  
they try every address in parallel and keep the one that answers  
first.   Because the fact is that the host has no way of making the  
judgment the Linux guys are attempting to have it make here - there is  
simply no way to know which address is preferable without trying.
