Try:

    fuser -m /mnt/cdrom/

to find a list of PIDs, and:

    fuser -k -m /mnt/cdrom/

to kill that set of processes.

You can use fuser to find out which processes are accessing any
given file on the system, generally speaking;  So, to see if 
anyone is accessing /tmp/filename, you can do:

    fuser /tmp/filename

to get a list of PIDs.
