I've added a patch to fix up some weirdness I was seeing running the activeresource unit tests. It's in lighthouse at http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/1620-fix-for-breaking-activeresource-unit-tests
Basically just due to the tests not explicitly requiring Benchmark.rb from the local working directory and ending up using an older incompatible version from gems instead.
Can I get someone to take a look?
