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.
