  37  * duplicate copy of the state up-to-date.
  38  *
  39  * This can change in two ways:
  40  * - With constant state objects we would only need to save a pointer,
  41  *     not the whole object.
  42  * - By adding a callback in the state tracker to re-emit state.  The
  43  *     state tracker knows the current state already and can re-emit it
  44  *     without additional complexity.
  45  *
  46  * This works as a proof-of-concept, but a final version will have
  47  * lower overheads.
