[ruby-talk:6359] break and http

Why doesn't break exit the iterator with http?
This prints out "got stuff" over and over.

   require 'net/http'
   host='127.0.0.1'
   url='/s.html'
   http = Net::HTTP.new(host)
   http.get(url) {|stuff|
     puts "got stuff"
     break
   }
   puts "all done"

This only prints "got stuff" once:

   file='/home/httpd/html/s.html'
   testfile=File.open(file)
   testfile.each {|stuff|
     puts "got stuff"
     break
   }
   puts "all done"
