I agree with this.  And by something going wrong, I would mean more
than just a validation failure in a place you might expect validations
to fail.  So to me, this pattern (which I've seen in the wild) or
variations of the same would smell bad:

def create
  @person = Person.new(params[:person])
  redirect_to :index
  # validation failed, go back to form
  redirect_to :new

If you go along with this, then the performance of begin/throw/rescue
in IronRuby shouldn't make much difference to the core performance of
your app.
