title: heroku toolbelt not running on Windows XP
body: <p>I downloaded the latest toolbelt for Windows; however, when I try to launch any heroku command from DOS I get: </p>
  
  <p>c:/Program Files/Heroku/lib/heroku/updater.rb:126:in <code>fork': fork() function is unimplemented on this machine (NotImplementedError)
          from c:/Program Files/Heroku/lib/heroku/updater.rb:126:in</code>background_update!'
          from c:/Program Files/Heroku/lib/heroku/updater.rb:111:in <code>inject_libpath'
          from c:/Program Files/Heroku/bin/heroku:19:in</code>'</p>
  
  <p>My purpose is to deploy a Play! app on heroku. I'm using Windows XP SP3. Anybody to enlighten me because I'm having headache.</p>
