O_DIRECT is reasonably common among modern Unixen (it is supported by
Linux, FreeBSD, and probably a couple of the commercial variants like
AIX or IRIX); it should also be reasonably easy to check for support at
configure time. It's on my TODO list to take a gander at adding support
for O_DIRECT for WAL, I just haven't gotten around to it yet.
