Create /tmp/a.  Create b as a symlink to a (``ln -s /tmp/a /tmp/b'').

Visit b.  Make some changes.  Save them.  In a shell window, change b
(or a) via touch or some other command that updates the file.  Make
more changes.  Try to save the file; you will get a notice that the
file has changed.

If instead you work with the file directly (a), you will immediately be
notified that the buffer has changed beneath you when you attempt to
make the first change.

It would be really nice if you were notified that the buffer has
changed as soon as possible.  Emacs 19.31 seems to follow the symlink
and keep track of the file as I would expect.
