When running mash via 'chrome --mash' *all* processes launched for individual services share the same command line. This means you can't do a 'ps' and see which process is running which service. This is painful. You can use --wait-for-debugger, but it would be really nice if we made it possible for the command line to show the service as well (we do this for mojo_runner, but mojo_runner is currently fundamentally flawed).
