  39  * duplicate copy of the state up-to-date.
  40  *
  41  * This can change in two ways:
  42  * - With constant state objects we would only need to save a pointer,
  43  *     not the whole object.
  44  * - By adding a callback in the state tracker to re-emit state.  The
  45  *     state tracker knows the current state already and can re-emit it
  46  *     without additional complexity.
  47  *
  48  * This works as a proof-of-concept, but a final version will have
  49  * lower overheads.
