Thanks, Bill.

Question for jmr at .  Is this an accurate description of the fetch behavior
now?

-Ping the list of master_sites and sort them based on ping response times
-Sourceforge, gnu, etc., special mirrors go after sorted url list
-MacPorts fallback mirrors at the end


Also, how many mirror types do we have defined?  Sourceforge, gnu, and
what else?
