Will do as soon as I get to it.

Btw. inotify doesn't require an open fd, so you could, in theory, change
the notification API so that the backend (dnotify,inotify,none) gets to
decide whether the fd should be kept open. With inotify, you could start
listening to events on all folders without the noticable overhead of
keeping fds open for all. But that would require a major change in the
code, so I didn't do it.
