 * There is no benefit to invoking multiple `close()` methods for the same response body.
 *
 * For synchronous calls, the easiest way to make sure a response body is closed is with a `try`
 * block. With this structure the compiler inserts an implicit `finally` clause that calls
 * [close()][Response.close] for you.
 *
 * ```java
 * Call call = client.newCall(request);
 * try (Response response = call.execute()) {

 * each event pair are used to link the event in case of concurrent or repeated events e.g.
 * `dnsStart(call, domainName)` → `dnsEnd(call, domainName, inetAddressList)`.
 *
 * Events are typically nested with this structure:
 *
 *  * call ([callStart], [callEnd], [callFailed])
 *    * proxy selection ([proxySelectStart], [proxySelectEnd])
 *    * dns ([dnsStart], [dnsEnd])
 *    * connect ([connectStart], [connectEnd], [connectFailed])
