Rails Delayed Job (DJ) 的奇怪问题

perform 里的 puts 一条也没有输出，求指点调用方法：

every(5.seconds, 'test.job') { Delayed::Job.enqueue TestJob.new }

lib/test_job.rb ：
class TestJob
  def perform
    puts "TestJob is start "
    puts "=========================================="
    puts "TestJob is end "
    puts "=========================================="
  end
end

执行结果：

17:49:35 clock.1  | I, [2013-01-30T17:46:44.923628 #25713]  INFO -- : Starting clock for 1 events: [ test.job]
17:49:42 clock.1  | I, [2013-01-30T17:49:42.997396 #25817]  INFO -- : Triggering 'test.job'
17:49:48 clock.1  | I, [2013-01-30T17:49:48.104511 #25817]  INFO -- : Triggering 'test.job'

楼上能否详细说明一下，DelayedJob 怎么重启，为什么不重启就不会运行呢？ https://github.com/collectiveidea/delayed_job 这里好像没提到呀。。。

########################################### clock.rb 文件定义如下： require File.expand_path('../../config/boot', FILE) require File.expand_path('../../config/environment', FILE) require 'clockwork' include Clockwork
