Use eventmachine with sinatra, why it will always quit?

Question

why it always quit when i run this ruby program ?
This is the ruby program:

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

when i run it, i got this:

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

Just run your Sinatra app under thin server and it will be fired with Eventmachine
