I believe this change fixes a bug which I've observed (in 7.1.6). In the old code there's an obvious race condition - _idleTimestamp could become zero after it is tested but before it is used to compute the idle expiry time. This would cause the connection to immediately be marked idle, and I've seen exactly that on a loaded multicore system handling a lot of short requests.
