// On Fuchsia, we assume that the Component Framework ensures that only a single
// Chrome component instance will run against a particular data-directory.
// This file contains a stubbed-out ProcessSingleton implementation. :)
//
// In future we will need to support a mechanism for URL launch attempts to
// be handled by a running Chrome instance, e.g. by registering the instance as
// the Runner for HTTP[S] component URLs.

// TODO(crbug.com/1370080): Implement these methods as appropriate.
