This scope is initialized once the Synchronizer starts because it will be a child of the parentScope that gets passed into the [start](start.md) function. Everything launched by this Synchronizer will be cancelled once the Synchronizer or its parentScope stops. This coordinates with [isStarted](is-started.md) so that it fails early rather than silently, whenever the scope is used before the Synchronizer has been started.
