[LAU] qjackctl fails to exit gracefully on UbuntuStudio 10.4

[John Ouzts]

Thanks Raine. My current understanding is that artsshell -q terminate does
in fact stop the pulseaudio processes but it does not release enough memory
(by removing the contents of /dev/shm) to allow a second startup of
qjackctl. The exact symptoms would vary with the amount of memory installed
in a given machine.
