I don't think that this will happen in reality; there are very few programs
using kqueue, and I think that most people don't treat the kqueue file
descriptors specially. I.e. if you ask jill-random if kqueue descriptors are
inherited on fork, she will probably say yes.

I don't know. I just dislike the special treatment. I think that the power
of unix comes from the fact that file-descriptors have all treated equally
for common operations. Yes, I know we have added all kinds of warts through
the years, but...
