I just created an SO account to offer some feedback to this answer to this question. Although I can apparently post a whole answer, or even edit others' answers (okay, it's moderated, but still), I can't post feedback to the one answer on that page I wanted to.
I don't have anything to add further to the other answers already posted, but I wanted to post a likely explanation as to why the poster of the linked answer didn't get a flush. (The calls to flush and close lack parens, so all you get is a reference to the function, not an invocation of it.)
The tips popup for the answers makes it clear that answers should answer the OP, not address other answers. I don't want to edit the answer at hand (even if it would be accepted), because it's not my post. Can I do anything, or should I wait until I've built up enough reputation?
