// Before running this file, do `touch foo` in the same directory.

var fs = require('fs'),
    sys = require('sys');

var f = fs.readFileSync('foo', 'utf8');
sys.puts("sync: " + sys.inspect(f));

fs.readFile('foo', 'utf8', function (err, data) {
  sys.puts("async: " + sys.inspect(data));
});

// Expected behaviour
//   both return the empty string: ''
//
// Actual behaviour
//   async returns an empty Buffer: <Buffer >
