  33 /* This looks like a lot of work at the moment - we're keeping a
  34  * duplicate copy of the state up-to-date.
  35  *
  36  * This can change in two ways:
  37  * - With constant state objects we would only need to save a pointer,
  38  *     not the whole object.
  39  * - By adding a callback in the state tracker to re-emit state.  The
  40  *     state tracker knows the current state already and can re-emit it
  41  *     without additional complexity.
  42  *
  43  * This works as a proof-of-concept, but a final version will have
  44  * lower overheads.
