fs.watch fired twice when I change the watched file

Question

 fs.watch( \'example.xml\', function ( curr, prev ) {
   // on file change we can read the new xml
   fs.readFile( \'example.xml\',\'utf8\', function ( err, data ) {

Similar/same problem. I needed to do some stuff with images when they were added to a directory. Here's how I dealt with the double firing:

var fs = require('fs');
var working = false;

fs.watch('directory', function (event, filename) {
  if (filename && event == 'change' && active == false) {
    active = true;

    //do stuff to the new file added

    active = false;
});

It will ignore the second firing until if finishes what it has to do with the new file.
