I've reaffirmed that OpenBSD's stance is that we'd prefer that MAP_ANON be standardized, explained the commit history of MAP_ANON and MAP_ANONYMOUS (thanks Ingo!), and also pointed out that "Advanced Programming in the UNIX Environment" recommends MAP_ANON: http://austingroupbugs.net/view.php?id=850#c2299 I'll update the thread if anything new develops.
