A rough idea would be to implement __destruct which cleans up the object:
Marco_Dom_Query extends Zend_Dom_Query
{
public function __destruct()
{
unset($this->_document);
}
}
Use it just like Zend_Dom_Query, keep unset($dom) in the loop and see
if this triggers __destruct() and really gets rid off the document you
added to the object. You could also check if memory_get_usage() grows
with each loop, or not.
