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/ferrocarril/spec-runner/spec/ruby/core/module/fixtures
    
    the code of the file until where you have to start completion: module ModuleSpecs
  def self.without_test_modules(modules)
  
    
    def await
      @mutex.synchronize do
        @state += 1
        if @state >= @count
          @state = 0
          @cond.broadcast
          true
        else
          @cond.wait @mutex
          false
        end
      end
