> The launcher library is currently restricted to launching apps as child 
> processes. That is fine for a lot of cases, especially if the app is running 
> in client mode.
> But in certain cases, especially launching in cluster mode, it's more 
> efficient to avoid launching a new process, since that process won't be doing 
> much.
> We should add support for launching apps in process, even if restricted to 
> cluster mode at first. This will require some rework of the launch paths to 
> avoid using system properties to propagate configuration.
