I believe that this also depends on how the file is updated.  Some
applications create a temporary file with the new (or changed) content and
then replace the old file with this one.

There are also cases where you can keep a file descriptor open to one file
that has no name (it existed once) and that was replaced.  

It all depends on how / who's generating and how / who's consuming the
information.
