I don't get this, though - or at least, I'd think those heuristics could be improved. If recent I/O usage is very light (typical desktop?), why not flush immediately? Delaying enables better throughput (via batching/reordering, I guess?), but if write rate is very low we don't care about throughput anyway, so there's no issue.
