1. Existing rspec-stackprof is "empty"
2. stackprof is written as a replacement for perftools.rb
3. Added an environment variable to conditionally run the profiler, it slows down test runtime by a couple of seconds for me.
4. Just add stackprof.rb to your spec/support folder, which is loaded on rails_helper.rb
