1077 * @note Notes on locking objects of this class:
1078 * SnapshotMachine shares some data with the primary Machine instance (pointed
1079 * to by the |mPeer| member). In order to provide data consistency it also
1080 * shares its lock handle. This means that whenever you lock a SessionMachine
1081 * instance using Auto[Reader]Lock or AutoMultiLock, the corresponding Machine
1082 * instance is also locked in the same lock mode. Keep it in mind.
