- Drops all events that happen before any changes are made (FSEventStream reports events from the past to a certain degree)
- Tests the same file twice in a row, since FSEventStream might coalesce events and report bogus changes
- Allows "modified" instead of "added" events, because FSEventStream does not allow to distinguish in some cases
isDir can be a huge performance issue when watching a network based directory and can effectively block the thread almost completely in case of frequent file changes. This does mean than high-level code now needs to perform the check manually, if required, and the free information provided by inotify goes unused.
