This is not "jackdbus" by itself, but the fact that the ALSA JACK
backend now uses some D-Bus based "reservation" code (defined by
PulseAudio developers). When the ALSA JACK backend starts, it ask for
the card and PA has to release it. When the ALSA driver stops, it
gives back the card.
So yes this reservation code is activated when JACK2 in compiled with
D-Bus, but it is not coded in the "jackdbus" executable.

Please be more specific on what could be done.
