* This still allows If-Modified-Since logic but does not
need to broadcast initialization values just because a
key fell out of cache. The value can differ between DCs
anyway via skew, this just lets them drift more. Actual
purge events are still broadcasted, which is what matters.
* The User class has now been simplified given this change.
* Added more general comments to getCheckKeyTime().

This class handles caching across distance sites where purges
must reach both. It also aims to make purging more reliable in
the face of network glitches and node consistent hash ejection.
