domxml close document routine

Overview: domxml does not include a close document routing to release memory after an xml document has been processed. I have added one. Purpose: I am using PHP's domxml functionality to parse thousands (17,000+) xml documents in a single request. The current implementation of domxml in PHP does not allow for xml documents to be closed, so memory is lost at more than 7KB/document during processing. I have been able to reduce this to 1KB/document by adding a close document routine to the PHP domxml extension and calling that close routine in my PHP scripts. Diff: Please see the patch files for my changes at the following URLs. http://robertoldham.com/php_domxml.h.php4.diff http://robertoldham.com/php_domxml.c.php4.diff http://robertoldham.com/php_domxml.h.php5.diff http://robertoldham.com/php_domxml.c.php5.diff Caveats: Lacking familiarity with PHP development, I am not sure that my implementation of the close routine is optimal. However, I have been using this code change in php-4.2.3, php-4.3.0 and php-4.3.1 for approximately 6 weeks without any problems. I am also unfamiliar with the process of getting a change reviewed and applied. If I have done anything wrong, or need to do additional things to follow this through, please let me know.
