Hum?

There's no notion of "new" or "old."  They're all just links to the
same contents.  Stow new data in there and the file contains new data,
and all the references are pointing to the same "new" contents.  That
doesn't seem to relate to hardlinks.

I suppose there could be confusion if several processes have the same
file open,  That doesn't have anything to do with hardlinks, though -
the confusion would be much the same even if all the processes have
the same filename in mind.
