    throw the initial exception which is most likely to be actionable.
 *  Fix: Retain interrupted state when throwing `InterruptedIOException`. A single interrupt should
    now be sufficient to break out an in-flight OkHttp call.
 *  Fix: Don't drop a call to `EventListener.callEnd()` when the response body is consumed inside an
    interceptor.
