1.Connection.prototype.attachListeners 里面 self.emit(msg.name, msg); 应该try {}catch(e){} 包起来
2.Client.prototype.connect 里面 con.on('error', function(error) -> return self.emit('error', error); 不能 return
3.这两个地方可以在任意一个地方try 或者 process.on('uncaughtException', function(err){}),否则 连上又断的时候导致process crash
4.client.on('error',,,
  client.connect(function(){}) 可能导致on的error收不到
5.DeAsync.js 对 seneca.http可行 对 seneca.tcp不行 可能原因是tcp的pipe代理等的问题

        // TODO: determine if these are all necessary / the best options
        // 1. name the function with something inteligible since some debuggers display the first part of each eval (Firebug)
        // 2. append the "//# sourceURL=location" hack (Safari, Chrome, Firebug)

Write After End error in node.js webserver

you need do sth

if(!res || !res.status || !res.socket || !res.socket.readable)return;

or next()

or 在回调函数前加 return 
or 把 response 作为参数传递给其他函数
