It is wrong. Spotlight uses fsevent, a private API which is presumably
related to kqueue in some fa****on. Kqueue simply wouldn't work for
spotlight since it doesn't allow monitoring entire trees of a filesystem
without opening a file descriptor on every directory within, which is
impractical when doing the entire hard drive.
