This is a protocol that file change notification classes should adopt.

That way, no matter whether you use Carbon's FNNotify/FNSubscribe, BSD's
|
|
kqueue or whatever, the object being notified can react to change
|
|
notifications the same way, and you can easily swap one out for the other
|
|
to cater to different OS versions, target volumes etc.
