 // The control flow includes most or all of the following,
 // depending on what is already registered:
 //  - creating a ServiceWorkerRegistration instance if there isn't
 //    already something registered
 //  - creating a ServiceWorkerVersion for the new version.
 //  - starting a worker for the ServiceWorkerVersion
 //  - firing the 'install' event at the ServiceWorkerVersion
