It's not actually RSpec-specific. I'll put it (or probably a hybrid
between your new code and my old code) into Wrong and you can use it
via the wrong rspec adapter.

def two
  rand(3)
end

require "rspec"
require "wrong/adapters/rspec"
describe "two" do
  it "should eventually be half of four" do
    eventually { (two + two).should == 4 }
  end
end

should work soonish...
