In Rails 3 how do I make a config yaml file reloadable?
===

I'm am in the process of upgrading a Rails app from 2.3.14 to 3.0.5 (intermediate step on the way to 3.1 then 3.2). 

There is a language translation system already built in the existing app. Eventually we may migrate it to use ruby/rails I18n, but not today.

The translation system loads a yaml file at startup that lives in config, like .../app/config/messages.yml. As it happens, one specific mechanism in this feature does not work in Rails 3, (specifically ApplicationController::Base.template). 

So, now I'm reworking the messages.yml file to work with the controller#action. It is a tedious process of changing template path to controller#action. It would be less tedious if I did not have to restart the server after every change.

Is there a way I can make Rails recognize that .../app/config/message.yml has changed and reload it?
