 // This is a work-around for the HasLatestProgressMarkers check's inherent
 // flakiness.  It's not safe to check that condition whenever we want.  The
 // safest time to check it is when the ProfileSyncService emits an
 // OnStateChanged() event.  This class waits for those events and updates its
 // cached HasLatestProgressMarkers state every time that event occurs.
 //
 // See the comments in UpdatedProgressMarkerChecker for more details.
 //
 // The long-term plan is to deprecate this hack by replacing all its usees with
 // more reliable status checkers.
