 *  Fix: Don't operate on a connection after it's been returned to the pool. This race occurred
    on failed web socket connection attempts.

We can use this listener to race a pair of concurrent HTTP requests:

```java
Request washingtonPostRequest = new Request.Builder()
    .url("https://www.washingtonpost.com/")
    .build();

            case "/v1/profile/info":
                return new MockResponse().setResponseCode(200).setBody("{\\\"info\\\":{\\\"name\":\"Lucas Albuquerque\",\"age\":\"21\",\"gender\":\"male\"}}");
        }
        return new MockResponse().setResponseCode(404);
    }
};
server.setDispatcher(dispatcher);
```
