No audio tracks.

cdp is the program I used to play audio. Once I've triggered an audio play
I can eject/remount/eject/remount and get nothing but disk errors until
cdp does an eject (I think it also does a stop on the play).

Being able as a user to screw (even though its not permanent) a mounted
file system. If this happens to be /usr on say a "live file system" based
machine you are in deep crap ;)

I would have expected EBUSY when it tried to do both at once.
