+     * To do this, number these states sequentially from zero, and note that

+     * <li>...meanwhile, {@code T2} also calls {@code CV.get(C)} and sees state {@code 2N}
+     * <li>{@code T2} quickly computes a similar time-dependent value {@code V1} and installs it on {@code CV.get(C)}
+     * <li>{@code T2} (or a third thread) then calls {@code CV.remove(C)}, undoing {@code T2}'s work
