The article struck me as such because the important point is not how glibc layers things, it's the conceptual detail that stdio buffers first and then flushes with write(). [You happened to pick a really bad libc to pick apart because a much simpler implementation is possible.] If someone saw your post having no idea they would have to parse it out of what you are saying, and probably get lost, because you did not say it plainly.
