### Key Design Patterns

1. **Fluent Builder Pattern**: `CurlRequest` uses method chaining for configuration
2. **Factory Pattern**: `Curl` class provides static factory methods for each HTTP method
3. **Resource Management**: `CurlResponse` implements `Closeable` for try-with-resources

                    final DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
                    factory.setFeature(org.codelibs.fess.crawler.Constants.FEATURE_SECURE_PROCESSING, true);
                    factory.setFeature(org.codelibs.fess.crawler.Constants.FEATURE_EXTERNAL_GENERAL_ENTITIES, false);

 * and we can't rely on classnames after proguard, so are probably best served by falling through
 * to a situation of trying our least likely noisiest options.

The `EventListener.Factory` also makes it possible to limit metrics to a subset of calls. This one captures metrics on a random 10%:

```java
class MetricsEventListener extends EventListener {
  private static final Factory FACTORY = new Factory() {
    @Override public EventListener create(Call call) {
      if (Math.random() < 0.10) {

        return kanaBuf.toString();
