Hmm. If people really do care, I guess we should spend the effort on
making those things unique.

I personally don't care about 32-bit any more, but it also feels wrong
to just say that it's ok depending on something on a 64-bit kernel,
but not a 32-bit one.

(very little) extra effort to do a 64-bit inode number.
