My proposed link() / unlink() procedure works only on platforms and file
systems, that support hard links. I totally forgot about the file system
issue, sorry. :)

Hard links won't work on a FAT32 mount point on Unix and probably not on
Samba shares, too. It might work on NTFS if the VFS implements it but
NTFS has a limited reference counter for hard links. It might be
possible that a rename() op would work but a link() op wouldn't.
