Shouldn't the directory watcher use FSEvents on OS X?
I've thought about it but it isn't compatible with other BSD platforms and has no docs about using it with kqueue, it ended up looking more complicated and unstable because I could read complaints everywhere I looked. It ended up putting me in a direction where I needed separate threads with their own event loops and communication through signals, which didn't fit in with what I was used to doing from what the other platforms offered.
I found the solution with kqueue's vnode, which acts like inotify. It doesn't have recursion nor file modification events when watching folders so individual files had to be watched and the directories checked against cache data every time an event came in. It seems a lot more flexible on the long run, and making feature additions / compatibility adjustments didn't sound like a nightmare on the long run.
