Zend_Http_Server will (partly) allow you to do this. Classes loaded before the server starts listening will be available to all child processes without further loading/parsing. Classes loaded by the child processes themselves will be freed/loaded each time.
I presume this is going to be a PHP implementation of http server which is obviously going to be used only during development not in production environments.
