node.js + sendfile = file serving++

gistfile1.js

http = require('http');
fs = require('fs');

fd = fs.openSync(__filename, 'r');
size = fs.fstatSync(fd).size;

server = http.createServer(function(req, res) {
        res.writeHead(200, {
                'Content-Length': size,
                'Content-Type': 'text/plain'
        });
        res._send(''); // force flush
        fs.sendfile(req.connection.fd, fd, 0, size, function(err, n) {
                console.log(arguments);
                res.end();
        });
});
console.log("Starting server.");
server.listen(8080);

I am trying to find linux's "sendfile" system call in node.js, it seems had been implement?~

It was removed in 2012, apparently broken between 2010 and 2012.
