What happens if you're not running a desktop graphical environment, so gvfs doesn't mount the disc? Basically, I'm worried that the drive may remain suspended after sr_open() returns. What happens if you use a program other than rhythmbox? There are (or used to be) programs which would issue the PLAY AUDIO command and then exit. The drive would continue playing even while the device file was closed. Do we want to drop support for that kind of behavior?
