Hmm... the "dead time" share parameter is in minutes, so you may have
trouble with this. It shouldn't be too hard to hack the code to recognise
"dead time = 15s", though, and could be useful to others too...

fuser -mv /cd/mount/point will tell you all the processes with open files
on that filesystem. fuser -km /cd/mount/point will (I think) kill all
processes accessing files on that filesystem.
For your cd changer script, you may like to look at the Linux autofs
automounter. I'm sure a bit of hacking should enable you to sort it out
