It might be interesting to try and flush the caches if "youngest" had
gone back in time. That is, if we know that the repository at a given
(UUID, dirent) had once had r200, and right now its youngest is r100,
then flush all caches related to that (UUID, dirent) pair.
Perhaps there are other invariants we could also check in a similar
manner, for example, the md5 of the text-rep of the node-revision of the
root directory at the (cached value of youngest) revision: if the md5
changes, then the cache is stale..
