* A child-execution is passed to the `asyncConstructor` method, which is set done when the method resolves or when the service has been deconstructed.
* A child-execution is also passed to the `getData`, `handleData`, and `handleDataError` config methods, which is set done as soon as the data has been retrieved and handled,
* hydration of the data has been requested, or when the service has been deconstructed.
*
* Now, when developing a service, the execution of the service can be very useful for other purposes. Child-executions can be created for all sorts of asynchronous
