Thanks. That's very useful and a bit depressing.

finalize_session (which writes the session to the DB) runs before
finalize_body (which writes the response to the client), so Catalyst already
does what you would like it to, and forcing a session write before running the
view is unlikely to help anything. I suspect either your database isn't
guaranteeing ordering, or the problem is somewhere other than where you're
looking.
