Subject: Infinite loop with Singleton mixin

This loops inifitely, but it doesn't seem like it should.

--
require 'singleton'

class SingleThing
  include Singleton
  def initialize
    @a = OtherThing.new
  end
end

class OtherThing
  def initialize
    @single_ref = SingleThing.instance
  end
end

a = SingleThing.instance

---

It looks as if the the SingleThing.instance method doesn't start
returning the allocated instance until initialize has *finished*, but it
seems to me it should start returning the allocated instance as soon as
initialize *starts*. Otherwise, methods called during initialize (and
the methods they call, and so on) can't refer back to the singleton
object using SingleThing.instance.

Any thoughts?
