 // A Syncer provides a control interface for driving the individual steps
 // of the sync cycle.  Each cycle (hopefully) moves the client into closer
 // synchronization with the server.  The individual steps are modeled
 // as SyncerCommands, and the ordering of the steps is expressed using
 // the SyncerStep enum.
 //
 // A Syncer instance expects to run on a dedicated thread.  Calls
 // to SyncShare() may take an unbounded amount of time, as SyncerCommands
 // may block on network i/o, on lock contention, or on tasks posted to
