Subject: Ruby Threads question

The following code is a slight modification of the code found at the top
of page 136 in the book "Programming Ruby The Pragmatic Programmers'
Guide" by Dave Thomas with Chad Fowler and Andy Hunt

#!/usr/bin/ruby -w

require 'net/http'

pages = %w(www.google.com www.slashdot.org www.mit.edu)
threads = []

for page_to_fetch in pages
        threads << Thread.new(page_to_fetch) do |url|
                h=Net::HTTP.new(url, 80)
                puts "Fetching: #{url}"
                resp = h.get('/', nil)
                puts "Got #{url}: #{resp.message}"
        end
end

threads.each {|thr| thr.join }

How come when I run this code, the following output goes line by line?
Fetching: www.google.com
Fetching: www.slashdot.org
Fetching: www.mit.edu
Got www.slashdot.org: Moved Permanently
Got www.google.com: OK
Got www.mit.edu: OK


Shouldn't the output be all done at once since the code is running in
parallel?
