[Rails] Plugin refresh time

Hello Anthony ~

For changes in a plugin to be picked up the app needs to be restarted.
 Imagine if the app had to reload every plugin on every request in
development mode? It would be quite a long wait for apps with many
plugins...

Don''t know if you saw this, but Geoffrey Grosenbach just released this:

It might have some tips.
