After I saw a presentation at BSDCon 2000 last year about the
	implementation of kqueue in FreeBSD, a few NetBSD developers
	present decided that it's definately worth a look for NetBSD.

	kqueue (aka `kevent') is a generic and scalable event
	notification facility, developed by Jonathan Lemon of FreeBSD.

	It's generic: you can monitor socket events, filesystem events
	such as `file ready to read', vnode operations such as `file has been
	deleted', `directory has been modified', signals delivered to a
	process, process creation/exit, etc.

If you want to claim it is a generic event mechanism it also
needs to support device events:  insertion, removal, errors,
etc.
