     *   which may lock-up the main thread.
     *
     * - `immediate`: Makes writeTask() and readTask() callbacks to be executed synchronously. Tasks
     *   are not scheduled to run in the next frame, but do note there is at least one microtask.
     *   The `immediate` setting is ideal for apps that do not provide long running and smooth
