So Lewk Macken has provided us with somewhat of a way out of that. His
fastest mirror plugin should help. It might not be foolproof but in a
number of the cases the mirror should be the same.

I guess the other option is we could download and store the mirrorlist
(if there is one in the repo stanza) and treat downloading the
mirrorlist the same as downloading the repomd.xml.

Then we could be assured of the ordering of the list. However, we're
talking about a fair bit more code now.

What do folks think?
