yes that would be nice. To send the closing </html> for example. The
standalone
php and php_mod should produce the same results.

The on_exit() handlers should not be restricted to do what they
want to...

condition in shutdown().
For some reasons PHP_CONNECTION_TIMEOUT condition is commented out in
zend_execute_API.c.
