 // An AppCacheService subclass used by the chrome. There is an instance
 // associated with each BrowserContext. This derivation adds refcounting
 // semantics since a browser context has multiple URLRequestContexts which refer
 // to the same object, and those URLRequestContexts are refcounted independently
 // of the owning browser context.
 //
 // All methods, except the ctor, are expected to be called on
 // the IO thread (unless specifically called out in doc comments).
