IteratorAggregate::getItterator should return instanceof Iterator: http://php.net/~helly/php/…

Namespace returns ArrayObject which does not implement Iterator: http://php.net/~helly/php/…

This is moot when using the namespace in a foreach since the foreach calls getItterator on the namespace, and again on the ArrayObject (Im think (?)).

Test:

Zend_Session::start();
$ns = new Zend_Session_Namespace('test-namespace');
assert($ns->getIterator() instanceof Iterator);

Possible Fix:

Zend_Session_Namespace 182:         return new ArrayIterator(parent::_namespaceGetAll($this->_namespace));
