Thanks,
I have code that mostly passes through to the default OS/X file system provider but includes some extensions to expose some of the OS/X native api’s. 
Not getting a lot of use I know of, but I run some other code off of it myself.
It lacks a WatchService ,my own attempt at a kqueue one for that coming up short.
So no actual native WatchService, which seemed a shame. 
I may try to make use of yours.
