Comment(by kevan):

 I'm attaching an updated patch with the costs of checking, verifying, and
 repairing files.

 I collapsed computational cost and network cost into one measurement where
 I thought it was appropriate (which was in most places), though I wonder
 if that was the right thing to do. It is nicer to read if we have just one
 rough cost for each operation, and doing so achieves the goal of telling
 users about the surprises associated with some operations, but it is
 imprecise. Granted, this file is imprecise -- people who really wanted
 precise information would probably go read the code -- but I wonder if
 we're losing too much.
