Rspec 2 (beta 9) transactional support for Sequel

Probably isn't ideal yet, but it works for me right now:

# in spec_helper.rb
class RSpec::Core::Example
  alias_method :original_run, :run

  def run(*args, &block)
    ret_val = nil

    Sequel::Model.db.transaction do
      ret_val = original_run(*args, &block)
      raise Sequel::Rollback
    end

    return ret_val
  end
end
