1097 * SnapshotMachine shares some data with the primary Machine instance (pointed

1099 * shares its lock handle. This means that whenever you lock a SessionMachine
1100 * instance using Auto[Reader]Lock or AutoMultiLock, the corresponding Machine
1101 * instance is also locked in the same lock mode. Keep it in mind.
