Stack Overflow questions with interesting answers are good bets for HN, but Stack Overflow questions about individual bugs with no answers aren't; they seem more like attempts to game Stack Overflow, and, at the very least, crud up HN. I actually flagged this.
I didn't think it would be interpreted that way. My bad. It seems like it's not a leak in the http library, just allocating memory and not releasing it sooner than expected.
