Opening the device.  xmcd appears to detect disk changes by locking the device 
so only it can perform an eject, closing the device before ejecting, and 
attempting to reopen until it succeeds.

I don't think the kernel can cope with a disk change while the device is open, 
mainly because of the fact that it's a block device (on e.g. Solaris you'd 
open the character device for the CDROM).
