how many of node.js developers are aware of that?

gistfile1.js

var http = require('http');
var counter = 0;
var server = http.createServer(function(req, res){
    var then = +new Date() + 9000;
    if (counter == 0) {
        while(+(new Date()) < then) {
        }
        counter = 1;    
       res.end("oh, hi");
   } else {
       res.end("hello world");
   }
});

server.listen(1337, 'localhost');
