When do you get ErrorKind::NotFound? If the parent doesn't exist?

Yeah that's the case where this is emulating create_dir_all instead of just create_dir, and if you create /foo/bar/baz but /foo/bar doesn't exist you'll get EEXIST (not found)

The compiler created a directory as part of `-Z incremental` but that may be hierarchically used concurrently so we need to protect ourselves against that.
