idle-hands is not really idle

idle-hands.js

var request = require('request');
var idlehands = require('idle-hands');
var timerCount = 0;
var idleCount = 0;

function repeat(cb) {
  setImmediate(function() {
    timerCount += 1;
  });
  idlehands.once('idle', function() {
    idleCount += 1;
    console.log(timerCount, idleCount);
    cb(cb);
  });
}

idlehands.once('idle', function(){
  repeat(repeat);
});
idlehands.start();

setInterval(function(){
  request('http://google.com');
}, 1000);

The output:

1 1
2 2

Such that the event idle will be called in every tick, it just run 3:run_idle function like this digram: http://readtrend.com/icon/5311
