Reduced test case:

require 'timeout'

class Foo
  include Timeout

  def foo
    timeout(1, StandardError) { sleep 10 }
  end
end

Foo.new.foo

Simple error. Whoever made this forgot these methods in Timeout could be called as module methods. If I remove the 'include Timeout' it all works because it hits the global 'timeout' method which properly passes in Timeout instance.

This is also broken in JRuby 1.7.x.
