Anybody know if collection at finalize time what the following code
(from the tutorial) does by default?

module MyLibrary
  class SomeObject < FFI::ManagedStruct
    layout :next,  :pointer,
           :name,  :string,
           :value, :double,

    def self.release(ptr)
      MyLibrary.free_object(ptr)
    end
  end
end
Thanks.
