与sinatra一起使用eventmachine，为什么它总是会退出？

Question

为什么当我运行这个ruby程序时它总是退出？
这是Ruby程序：

require 'rubygems' 
require 'eventmachine' 
require 'thread' 
require 'sinatra' 

Thread.new do 
    EventMachine.run do 
     EM.add_periodic_timer(1) do 
      #do some things 
     end 
    end 
end 

get '/' do 
    'hello' 
end 

当我运行它，我得到这个：

lynn@ubuntu:~/Test$ ruby em1.rb

当我运行这个Ruby程序有人不干了，为什么呢？在这里，我想要一个线程来定期对http请求做一些事情！我该怎么做 ？

只需在thin服务器上运行您的Sinatra应用程序，它将与Eventmachine一起启动
