warning

DEPRECATION WARNING: Setting a Proc or an object that responds to call in response_body is no longer supported. (called from realtime at /Users/trobrock/.rvm/rubies/ruby-1.8.7-p352/lib/ruby/1.8/benchmark.rb:308)

I am seeing the same warning from similar code -- do you know how to fix it?

I have not figured out a decent way of fixing this yet.
