After some discussions in Dublin I decided to get rid of the interfering systems handler. No more killing of stuff like the mediamanager or suseplugger. I replaced all that with a single lsof check which recommends to the user to quite the processes using the device.

Thanks to all the exclusive open patches for packages like cdparanoia we cannot allow a single other application opening a device even only for reading.

I really don't get why they keep adding these patches. Anyway, this solution should work now. It should even fix the problems with creating an audio CD from a collection of tracks from other CDs.

Maybe this commit breaks compilation. I don't know. There is a lot of unfinished stuff in my local checkout. I hope to get that clean up today.
