1432	Magic Folder on Mac OS X and other BSDs	davidsarah		"The Magic Folder feature currently only works on Linux (where it uses inotify to detect filesystem changes), and Windows (where it uses `ReadDirectoryChangesW`). This ticket is about supporting the same feature on Mac OS X and possibly other BSD-based operating systems.

Mac OS X has the [http://en.wikipedia.org/wiki/FSEvents fsevents], and all BSDs including Mac OS X have kqueue/kevent. If I understand correctly, neither fsevents nor kqueue/kevent give notifications of which files have changed, so the implementation will have to scan the directory and look at last-modified times to determine that. (This is occasionally also necessary for correctness on Linux and Windows; see #1430.)
