One of the output buffering tricks described on
http://us2.php.net/register_shutdown_function works with drupal.  Note
for this, drupal caching needs to be off since cache.inc already has
its own ob_end_flush().

add this at the top of drupal index.php:
header("Connection: close");

and at the bottom add this:

$size = ob_get_length();
header("Content-Length: $size");

You can see that the session is still alive 15 seconds after you
finished loading the page, and it adds a message which will display on
subsequent page loads.
