Inotify

I think I could fix an inotify issue - https://code.google.com/p/go/issues/detail?id=2483
see https://github.com/chamaken/inotify
And then I am glad if I can backport it to your fsnotify. Would you review the patchs?

I don't mind doing minor cleanup as part of my [merging process](http://blog.spreedly.com/2014/06/24/merge-pull-request-considered-harmful/). More concerned with functionality.

Of course running gofmt and checking for typos is always appreciated. :-)
