So, in general, the way to detect hard links requires both objects to be open at the same time? I was sure it was enough to stat(), and check (st1.st_ino == st2.st_ino && st1.st_dev == st2.st_dev).
Admittedly, one of the object could be renamed or deleted in that time so it's not 100% reliable on changing filesystems.
Ah well.
