I have found the solution by overwriting the default global agent. One possibility is to set maxSockets:1:

var http = require( "http"),
    agent = new http.Agent( {maxSockets: 1} ); // <-- this is new

function httpRequest( callback ) {
    var options = {
            host: 'localhost',
            port: 80,
            path: '',
            agent: agent // <-- and this is new
        },
...

With this correction the example above works. But I still had the EADDRNOTAVAIL issue within my production code, so setting the agent to false did it finally:

var http = require( "http");

function httpRequest( callback ) {
    var options = {
            host: 'localhost',
            port: 80,
            path: '',
            agent: false // <-- here
        },
...

I have posted this issue also on GitHub.
