PulseAudio -> JACK connection in Oneiric

I gave the PulseAudio/JACK integration a quick check in Ubuntu 11.10,
basically I started banshee playing through PulseAudio, and wanted it to
play to JACK.
I had these obstacles to overcome:
1) There is still a pasuspender wrapper script when starting qjackctl!
Instead of starting "qjackctl", you'll have to start
"/usr/lib/qjackctl/qjackctl.real" instead. (This is particularly
annoying as I remember having removed a similar script earlier, but
apparently it has been re-added by Alessio?)
2) When starting JACK server (from qjackctl), sound from PulseAudio
stops, but it complains that the sound device is still in use. This
seems to be a timing issue. Just stop and start the server a second time
and it works.
3) I used pavucontrol to reroute Banshee's audio stream, so that in
pulseaudio, Banshee's is routed to the JACK sink.
