    You can only do that if the cowid object has a pointer to the last
    remaining reference to it. That's possible, but more complicated and
    would incur a little more I/O per cow operation.

    fsck could do it. It's not a big deal though: simply looking up the
    inode through the last remaining path can also clean it up. Until
    them, it's very little space used: the same as a short symlink.
