I took the time to check out the kqueue code in Advanced Mac OS X
Programming (Hillegass & Dalrymple) and they don't show any fd
closing.  That aspect seems to not be mentioned at all.

The book does give a useful description of using kqueue for signal,
socket and filesystem event handling, for those who are interested.
