You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: classes.rb
    path of file: ./repos/artichoke/artichoke-backend/vendor/ruby/spec/ruby/core/thread/fixtures
    
    the code of the file until where you have to start completion: module ThreadSpecs

  class SubThread < Thread
    def init
    
  def self.status_of_running_thread
    t = running_thread
    Thread.pass while t.status and t.status != "run"
    status = Status.new t
    t.kill
    t.join
    status
  end
