I have to at least partly disagree here. Some sysctl names are descriptive,
not all are. I'd argue that many of them aren't *sufficiently* descriptive,
and a short textual description would be helpful.

You and I may know what net.inet.tcp.log_in_vain means - but I think it's
not at all obvious unless you look at the source. I definitely didn't know
what net.inet.ip.fastforwarding was until I looked at the source.

You can also argue that nobody should change sysctl values until they have
looked at the source. Do we really want that? It seems awfully restrictive.
