The reason it didn't mount is because you were probably still in the
/floppy directory.  Watch:
RoOt@femto[~]$ umount /cdrom
RoOt@femto[~]$ cd /cdrom/
RoOt@femto[/cdrom]$ touch linguini
RoOt@femto[/cdrom]$ mount /cdrom
mount: /dev/scd0 already mounted or /cdrom busy
RoOt@femto[/cdrom]$ fuser -v /cdrom

                     USER       PID ACCESS COMMAND
/cdrom               root     15679 ..c..  bash
RoOt@femto[/cdrom]$ cd /
RoOt@femto[/]$ mount /cdrom
RoOt@femto[/]$ (success)
