Node.js: How to add event handler to Connect/Express Server?

I want handle EADDRINUSE how it is described in API Doc nodejs but connect/express did not call the error event handler.

here is a example:

var connect = require('connect');
var app = connect();

app.use(function(req, res){
    res.end('hello world\n');
});

app.on( 'error' , function(e) {
    console.log('error event handler called');
});

app.listen(3000);

if I start the server two times, I got
throw arguments[1]; // Unhandled 'error' event

I tested it with connect 2.7.2.

Since version 2.x, connect() is no more a constructor for a net.Server. The 'net.Server' will be returned by the function listen(...).

So to get the example working, it should look like this:

var connect = require('connect');
var app = connect();

app.use(function(req, res){
    res.end('hello world\n');
});

app.listen(3000).on( 'error' , function(e) {
    console.log('error event handler called');
});
