Try this out Brian:

require 'timeout'

class TooMuchTimeException < Exception;end

class Class
  def time_limit(hash)
    hash.each do |name, limit|
      m = instance_method(name)
      define_method(name) do
        timeout(limit, TooMuchTimeException) do
          m.bind(self).call
        end
      end
    end
  end
end

class Foo
  def calc1
    1
  end

  def calc2
    sleep(7)
    2
  end

  time_limit :calc1 => 20, :calc2 => 5
end

f = Foo.new
p f.calc1
p f.calc2
