> The public constructor on StoppableCountDownLatch reads a system property each time.
> This is a synchronized operation and every time we wait for a response from a peer we create one (In ReplyProcessor21). We don't expect this system property to change on a running jvm so we could read it once and cache the result to improve performance.
> The expression that reads the system property is: MILLISECONDS.toNanos(Long.getLong(RETRY_TIME_MILLIS_PROPERTY, RETRY_TIME_MILLIS_DEFAULT))
