fs/super.c:

    /* Forget any remaining inodes */
    if (invalidate_inodes(sb)) {
        printk("VFS: Busy inodes after unmount of %s. "
           "Self-destruct in 5 seconds.  Have a nice day...\n",
           sb->s_id);
    }

That's what happens if you eject a CD. The box won't explode though.
