Yes, but it does so stupidly.

You can be notified when something changes in a directory, but it is up to you
to do an opendir(or rewinddir on a previously opened dir), and iterate thru
all the files, comparing with a previous list, to find what changed.

The 'api', as it were, only supports the notification.  It has no payload to
go along with it.
