nope. A mirror could be in the middle of a sync. We cannot control HOW
the mirrors sync the data. We can't know. But this keeps users from
being bounced to sites with multiple, out of date metadata.
Additionally, if they're given a whole set of mirrors it means that the
mirrors they get will be 'roughly' more current then never pruning the
mirrors at all.

The only other option we have is checking every file and that will take
WAAAAAY too much time and bandwidth.

I'm open to other suggestions.
