public void mark_busy ()
Increases the busy count of this.
Use this function to indicate that the application is busy, for instance while a long running operation is pending.
The busy state will be exposed to other processes, so a session shell will use that information to indicate the state to the user (e.g. with a spinner).
To cancel the busy indication, use unmark_busy.
The application must be registered before calling this function.
