That (and thanks for the AIX note) is interesting, but I don't see that it makes backup programs work right. It seems that the current man page caution about consistency is correct, and that it would be great if someone added a cache invalidate on close. (It's a little scary to touch this code in terms of how much it could mess people up.)
