In that case I think the best thing would be to start a fresh ruby 
process, otherwise you will have all the old models etc already loaded.

This works for me on OS X:

Wx::App.run do
  def self.on_exit
    exec("ruby #$0")
  end
  ....
end

This assumes the environment's ruby is the right one to start the app. 
Note that you'll want to have your editor handy to comment out the 
restart else you'll end up in a permanent loop. In your case, you'll 
want to wrap the exec in some sort of conditional which checks for 
restart after upgrade.

If it's an open app, I'd be interested to hear about/see examples of 
code updating over net whenever you're ready.
