 // This method gets the instance of each ServiceFactory. We do this so that
 // each ServiceFactory initializes itself and registers its dependencies with
 // the global PreferenceDependencyManager. We need to have a complete
 // dependency graph when we create a browser state so we can dispatch the
 // browser state creation message to the services that want to create their
 // services at browser state creation time.
 //
 // TODO(erg): This needs to be something else. I don't think putting every
 // FooServiceFactory here will scale or is desirable long term.
