Should emit events.

Emission.js

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

var Emission = module.exports = function () {
  events.EventEmitter.call(this);
  
  this.cycles = 0;
};

sys.inherits(Emission, events.EventEmitter);

Emission.prototype.cycle = function () {
  this.emit('recycle', ++this.cycles);
  
  var self = this;
  
  setInterval(function() {
    self.cycle();
  }, 0);
};
