This version collects the events in a separate thread, and doesn't gobble up events. So hopefully it's more robust, in addition to being easier to read. One downside of using the "watchdog" module is that it only exposes file/dir modification events. So if I ever want to keep track of opened files, I'll have to call inotifywait again.
