-// This class is used to manage the lifetime of ServiceWorkerProviderHosts
-// created during navigation. This is a UI thread class, with a pendant class
-// on the IO thread, the ServiceWorkerNavigationHandleCore.
-//
-// The lifetime of the ServiceWorkerNavigationHandle, the
-// ServiceWorkerNavigationHandleCore and the ServiceWorkerProviderHost are the
-// following :
-//   1) We create a ServiceWorkerNavigationHandle on the UI thread with a
-//   service worker provider id of -1. This also leads to the creation of a
-//   ServiceWorkerNavigationHandleCore with an id of -1.
-//
-//   2) When the navigation request is sent to the IO thread, we include a
-//   pointer to the ServiceWorkerNavigationHandleCore.
-//
-//   3) If we pre-create a ServiceWorkerProviderHost for this navigation, its
-//   ownershipped is passed to the ServiceWorkerNavigationHandleCore. The
-//   ServiceWorkerNavigationHandleCore id is updated.
-//
-//   4) The ServiceWorkerNavigationHandleCore informs the
-//   ServiceWorkerNavigationHandle on the UI that the service worker provider
-//   id was updated.
-//
-//   5) When the navigation is ready to commit, the NavigationRequest will
-//   update the RequestNavigationParams based on the id from the
-//   ServiceWorkerNavigationHandle.
-//
-//   6) If the commit leads to the creation of a ServiceWorkerNetworkProvider
-//   in the renderer, a ServiceWorkerHostMsg_ProviderCreated will be received
-//   in the browser. The ServiceWorkerDispatcherHost will retrieve the
-//   ServiceWorkerProviderHost from the ServiceWorkerNavigationHandleCore and
-//   put it in the ServiceWorkerContextCore map of ServiceWorkerProviderHosts.
-//
-//   7) When the navigation finishes, the ServiceWorkerNavigationHandle is
-//   destroyed. The destructor of the ServiceWorkerNavigationHandle posts a
-//   task to destroy the ServiceWorkerNavigationHandleCore on the IO thread.
-//   This in turn leads to the destruction of an unclaimed
-//   ServiceWorkerProviderHost.
