- * duplicate copy of the state up-to-date.  
- *
- * This can change in two ways:
- * - With constant state objects we would only need to save a pointer,
- *     not the whole object.
- * - By adding a callback in the state tracker to re-emit state.  The
- *     state tracker knows the current state already and can re-emit it 
- *     without additional complexity.
- *
- * This works as a proof-of-concept, but a final version will have
- * lower overheads.
