Please elaborate.
Do you mean you just shutdown the other machine ? Or that you umount the
cdrom ?

This shouldn't be necessary. The problem is with nfs semantics and the
linux implementation (fstab + /proc).
If the cdrom is NOT mounted by ANYBODY then you should be able to umount
it on your end and get it out.

Other than that you can try to shutdown nfsd (don't count on that, I haven't
tried it)

Inform the other parties that they don't forget to umount the cdrom after
use ?  ;)
