1095 * SnapshotMachine shares some data with the primary Machine instance (pointed
1096 * to by the |mPeer| member). In order to provide data consistency it also
1097 * shares its lock handle. This means that whenever you lock a SessionMachine
1098 * instance using Auto[Reader]Lock or AutoMultiLock, the corresponding Machine
1099 * instance is also locked in the same lock mode. Keep it in mind.
