Lol, author's thought process mirrored mine as I read the article, as I was reading I was thinking, 'doesn't kqueue support that?... and then a section on kqueue. Then I was thinking to myself, so how does the Linux implementation do it then?... was just about to start trawling the source code when 'A parenthesis..'
Great article. Sorry to say though, Windows does manage all this in a more consistent way - but I guess they had the benefit of a clean slate.
signalfd / process descriptiors are the Windows style mechanism... what is missing are a few things like 'spawn' that returns a fd directly (eliminating races...)

there is no race from the parent
the pid will not be reused until you either handle sigchld or wait
