I'm not sure what your "good enough" algorithm actually does.
Consider also the fact that e.g. on Linux you can mount the same
filesystem several times, in several places. There is no _one unique_
canonical name for a file.

Personally I'd just like a simple stat() for each (non-symlink) file
and remembering their st_dev and st_ino values. I don't know how this
would be emulated on other operating systems, though.
