Title: Avoid double module inclusion.

This would fix [rails-dev-boost](https://github.com/thedarkone/rails-dev-boost) (a Rails plugin that patches `ActiveSupport` to only reload `.rb` files that have actually changed for faster development mode).

The code in the pull request can be changed/rewritten.
