低级 JSGI 适配器实现。
创建流异步响应。返回的响应对象既可以在当前线程中同步使用，也可以从另一个线程异步使用，即使原始线程执行完毕后也是如此。 AsyncResponse 对象是线程安全的。
要在 Servlet 3.0+ 容器内启用异步支持，可能需要 web.xml 部署描述符中的其他 <async-supported>true</async-supported> 元素。这表明 Ringo 的 JsgiServlet 支持异步请求处理。
const response = new AsyncResponse(request, 10000);
response.start(200, {"Content-Type": "text/plain"});
// this functions returns a ringo promise
doSomeAsyncStuff().then(function(data) {
// write out result
response.write(data);
response.close();
}, function() {
// just close the connection in case of an error
response.close();
});
return response;| Object | request | the JSGI request object |
| Number | timeout | time in milliseconds in which the async operation has to be completed; otherwise the request is aborted by the Servlet container. A negative value lets the async operation never time out. Defaults to 30 seconds. |

| Function|String | functionObj | the function, either as function object or function name to be imported from the module moduleId. |
