You don't have to wrap all your code in a call to `Fiber()`

full classic node-server sample:

    var http=require('http'), wait=require('wait.for');

    http.createServer(function(req, res) {
      wait.launchFiber(handleRequest,req, res); //run in a Fiber, keep node spinning
    }).listen(8080);


   //in a fiber
   function handleRequest(req, res) {
     try {
       res.writeHead(200, {'Content-Type': 'text/html'});
       res.end(
       "<h1>Demo page</h1>" 
       + "<p>"+ wait.for(fs.readFile,'/etc/somefile') +"</p>"
       + "<p>"+ wait.for(fs.readFile,'/etc/otherfile') +"</p>");
     }
     catch(err) {
      res.end('error '+e.message); 
     }
   }
