CLIENTS:
        To be able to make use of realtime scheduling clients may
        request so with a small D-Bus interface that is accessible on
        the interface org.freedesktop.RealtimeKit1 as object
        /org/freedesktop/RealtimeKit1 on the service
        org.freedesktop.RealtimeKit1:

                void MakeThreadRealtime(u64 thread_id, u32 priority);

                void MakeThreadHighPriority(u64 thread_id, s32 priority);
