var processOnTime = function ( next, delay ) {
  var d = delay;
  
  if ( ! next ) {
    throw new ReferenceError();
  }
  
  if ( ! d || isNaN ( d ) ) {
    d = 200;
  }
  
  if ( this.timeoutID ) window.clearTimeout ( this.timeoutID );
  this.timeoutID = setTimeout ( function () {
      next();
  }, d );
};
