74 // The states in chronological order are: previous, current, next, and mutating:
75 // previous read-only, observer can compare vs. current to see the subset that changed
78 // previous = current
80 // and the slot formerly used by previous is now available to the mutator.
83 // before the mutator, there are no previous, current, or next states. And even if the observer
84 // starts execution after the mutator, there is a next state but no previous or current states.
86 // and it will have to deal with the case where there is no previous state.
137 // If a new state has not pushed by mutator since the previous poll,
139 // The previous state pointer is guaranteed to still be valid;
140 // this allows the observer to diff the previous and new states.
149 // this new mutation will be squashed together with the previous one.
