 // StatusController handles all counter and status related number crunching and
 // state tracking on behalf of a SyncSession.
 //
 // This object may be accessed from many different threads.  It will be accessed
 // most often from the syncer thread.  However, when update application is in
 // progress it may also be accessed from the worker threads.  This is safe
 // because only one of them will run at a time, and the syncer thread will be
 // blocked until update application completes.
 //
 // This object contains only global state.  None of its members are per model
 // type counters.
