I think I found the problem. It's something I was unsure about
earlier but forgot about. The notifications are registered for the
file path as the object. That's wrong, as the object is compared
using pointer equality, /not/ isEqual. I'm not sure how to fix this
though, as the fileName of the document can change when the file is
moved or deleted, while we should still observe those changes. Also
UKKqueue does not ensure that it always uses the same instance for
the notification name, so it's also wrong.

Is it much of an overhead to have one UKKqueue for each document?
