[Catalog-sig] Mirror list detection/construction - PEP 381

I think you misunderstood the question. The issue is not at all what 
mirrors to use once you know what they are - the question is how to find
out what mirrors exist in the first place.

When you know what they are, I do support the idea of trying them all
simultaneously, though not in parallel. With sockets, you can have many
open without having to use threads.

I'll post some code that does that shortly.

Martin
