The other thing I was going to ask you about is using posix_fadvise as an alternative to O_DIRECT for the xlog. O_DIRECT is, AFAIK, linux-only, whereas there are "direct write" fadvise flags which work on multiple OSes.
What flags are those? I don't see any posix_fadvise flags that would do anything like O_DIRECT.
