Nope, this is a GNU extension to fcntl. File change notifications are done
with EVFILT_VNODE using kqueue(2). Directory changes have no interface that I
know of. You might wanna take a look at how devel/gamin handles this,
specifically the kqueue implementation.
Problem with today's modular software: they start with the modules
and never get to the software part.
