How do they deal with the x-only directory problem (you can't open() it
but there's no reason you shouldn't be able to use it with calls like
these)?  I've often wanted to be able to open . and then use the fd,
usually for fchdir(), but potentially for these.  Does Solaris have an
O_NOACCESS or something to deal with that?
