    hand it off to another thread to write to it after `writeTo` returns.

    The `EventListener` may now see requests and responses interleaved in ways not previously
    permitted. For example, a listener may receive `responseHeadersStart()` followed by
    `requestBodyEnd()`, both on the same call. Such events may be triggered by different threads
    even for a single call.

    // Confirm the events occur when expected.
    listener.takeEvent(CallStart::class.java, 0L)
    listener.takeEvent(ConnectionAcquired::class.java, applicationInterceptorDelay)
    listener.takeEvent(RequestHeadersStart::class.java, networkInterceptorDelay)
    listener.takeEvent(RequestHeadersEnd::class.java, 0L)
    listener.takeEvent(RequestBodyStart::class.java, 0L)
    listener.takeEvent(RequestBodyEnd::class.java, requestBodyDelay)

    assertThat(response.code).isEqualTo(200)
