I didn't find a PR, but there was at least some discussion when I
added the pkgsrc Python fix, starting here:
http://mail-index.netbsd.org/current-users/2012/08/15/msg020907.html

While I don't think that it causes these problems, an obvious
deficiency is that our kernel semaphores get inherited to child
processes, while Posix says that they should be closed on exec.
