AIUI, the tree will only be walked over during update composition and applying 
an update to the mirror (updates are done out-of-tree so that there is no 
catching a server "with its pants down" per se.

Yes, we'll have to keep an eye on this. As things come down from the tubes, the 
hashes should be working so they'll most likely be waiting on the network to 
get done with its files.
