- // Important implementation note:

- // Actions only execute once by default, unless rescheduled from within the

- // as mimic traditional recursion but across asynchronous boundaries.
- //
- // However, JS runtimes and timers distinguish between intervals achieved by
- // serial `setTimeout` calls vs. a single `setInterval` call. An interval of
- // serial `setTimeout` calls can be individually delayed, which delays
- // scheduling the next `setTimeout`, and so on. `setInterval` attempts to
- // guarantee the interval callback will be invoked more precisely to the
- // interval period, regardless of load.
- //
- // Therefore, we use `setInterval` to schedule single and repeat actions.
- // If the action reschedules itself with the same delay, the interval is not
- // canceled. If the action doesn't reschedule, or reschedules with a
- // different delay, the interval will be canceled after scheduled callback
