Makes sense. I have only used kqueue on macos to monitor a small number of files and I find it quite painful to use and the semantics were confusing, not sure if it is different on say freebsd. Just as a heads up, one of the strange fsevents issues is that it fails if you register two directories where one directory is a prefix of the other. So say that you want to monitor directories $ROOT/foo and $ROOT/fo and you register an event stream first with $ROOT/foo and then $ROOT/fo, you will only receive events for paths in $ROOT/fo and no events for paths in $ROOT/foo (I just double checked that this is still the case in Monterey at least). I never bothered to report this to apple but worked around it by just registering a stream with $ROOT if I detected that one path name was a substring of another.
