built-in o bjects APC or serial ization‏

Hi everybody, I am a Certified Zend Engineer with almost 10 years of PHP development experience but for some reason I've never asked question to this ML. As subject says, I would like to know if there a generic extension/3rd parts/solution to save the state of a built-in PHP object. I perfectly know that __sleep and __wakeup or ... implements Serializable { ... } could allow me to store and retrieve serialized data but what I did not expect is that APC just behaves as serialize and "nothing more" than that. Here there is a quick explanation: $xsltp = new XSLTProcessor; $xsltp->importStylesheet( DomDocument::load('random.xsl') ); // no way to store the variable here with its live state // without re-importing stylesheet on __wakeup or unserialize echo $xsltp->transformToXML( DomDocument::load('random.xml') ); I agree that this built-in stuff could be consider a weird case but I cannot believe that with all these new classes there is no solution to truly hibernate instances state. As summary, I wonder if any of you knows a solution or, if any, when (and if) are you planning to add this feature.
