I used to work on the PHPLIB project, and the user's session ID
was always very stable and consistent. I never saw a support
request about lost sessions that wasn't caused by a bad
configuration of either browser or more usually the application.

So I think that if the session ID has changed from when the
form is shown to when it is submitted, that is a good enough
reason to invalidate the submission.

+1 to use session_id().
