Timeouts in kernel code for these drivers are long. The typical minimal
timeout is 7 seconds, though one timeout in drivers/cdrom/cdrom.c is 50
minutes! (It's a write thing though).

I've just submitted a driver to the kernel for a proprietary cdrom device
and I could not see any simple way round the sort of problems you
encounter (eg if you take a disk out on mine, it repeatedly times out
severy 7 seconds trying to read a sector).

Others may have a different view but I think beyond trying 'sudo eject'
there might not be much you can do.
