No offense to you but that article is very poorly written. It seems like someone abducted the author mid-article and pressed the publish button :)

There are some technical inaccuracies that make it hard to look past as a coder (mixing up POSIX and UNIX, talking about unexpected behavior as a bug). However, I think the author did an accurate job on the high-level tenor of the article and touched on a critical meta-point about this bug.
