The manual page says:

"Inotify monitoring of directories is not recursive: to monitor
subdirectories under a directory, additional watches must be created."

Therefore, if inotify per se does not support this feature (aka
recursive monitoring of trees), I would not worry at all about
implementing something like this in kqueue land.  After all, no
program is gonna use this feature if inotify does not have it!
Creating additional watches for all subdirectories in a tree seems a
reasonable compromise even if it takes many filedes.
