Come to think of it, it's wasted on any system that conforms to POSIX,
since POSIX requires that open-with-write-access must fail on
directories. I think I'm responsible for that O_WRONLY business, but
I don't recall what I tried it out on -- perhaps SunOS 4?
I don't think it's worth worrying about non-POSIX systems, so I'll
prepare a patch that undoes that stuff (both here and elsewhere).
There are some related things that need normalizing, too, e.g.,
whether to open directories with O_NONBLOCK, O_DIRECTORY, and the like.
