> The timeout passed to {{WorkerCoordinator.poll()}} can overflow if large enough because we add it to the current time in order to calculate the call's deadline. This shortcuts the poll loop and results in a very tight event loop which can saturate a CPU. We hit this case out of the box because Connect uses a default timeout of {{Long.MAX_VALUE}}.
