关于 graceful 与 domain-middleware 功能上的差异的疑问

@fengmk2 最近我在学习 Express 的错误处理方面的内容，了解到 graceful 与 domain-middleware。比较了下两者的源代码，大体上的逻辑是一样的，唯一的区别是 domain-middleware 对当前出错的请求可以返回一个信息，但是我在 graceful 中没有找到，这个应该是基于 process.on('uncaughtException') 的解决方案的一个缺陷吧（希望我没有遗漏）。如果说想把这个缺陷填补上，还有别的办法吗？不知道阿里这边是怎么解决的？

Support multi servers close.

graceful({
  server: [app, hsf, rest],
  killTimeout: 30000,
});

关于 domain 模块不再使用的疑惑

这个 readme 里面写着 domain 的介绍，可是源码里面已经没有 domain 的代码了。是否 readme 比较旧？
另外，graceful 此模块目前还推荐使用吗？

When uncaughtException emit, let server http res set close connection header.

http.js will keepalive the connection: https://github.com/joyent/node/blob/master/lib/http.js#L619

We need to set Connection: close header.
