-// An UpdateApplicator is used to iterate over a number of unapplied updates,
-// applying them to the client using the given syncer session.
-//
-// UpdateApplicator might resemble an iterator, but it actually keeps retrying
-// failed updates until no remaining updates can be successfully applied.
