Are you sure you understood how redirecting and sessions works? A script
that has sent a header redirect _can_ continue on and one, doing heavy
work that lasts for an x amount of time. The session will only be closed
automatically when the script ends. If the user is allready requesting the
following page it might slow him down considerably, as the session data
isn't made available untill the end of that renegade script...

So, if a session is no longer needed, it's a wise idea to close is, just
not very necessary in your normal garden variety of PHP scripts.
