Request profiling - login and authenticity token

I was doing Request profiling like Ryan Bates showed on railscasts
(http://railscasts.com/episodes/98-request-profiling) and I wanted to
profile some update action.

I've prepared a script: http://pastie.org/267554

After running request profiler I saw InvalidAuthenticityToken error. I
disabled it and then realized that user is not authorized while
profiling. So I've skipped login_required and authorization. But...
current_user data is needed in some of the actions.

I definetely have to provide valid user. Auth token isn't important,
but still, disabling it on while profiling isn't the best solution

How to handle it the rails way?
