11  * LUO provides the infrastructure to preserve specific, stateful file
27  *   - preserve(): The heavyweight operation that saves the file's state and
31  *   - unpreserve(): Cleans up any resources allocated by .preserve(), called
48  *    handler, calls its .preserve() operation, and creates an internal &struct
133  *                 state that is not preserved. Set by the handler's .preserve()
152  * and the serialized state handle returned by the handler's .preserve()
210  * 4. Calls the handler's .preserve() operation, which saves the file's state
228  *         Other erros might be returned by .preserve().
