Rails 3 reload! broken - potential fixes?

In Rails 3.03 the reload! method in the console seems to be broken. If
your app gets large, this becomes annoying because you have to wait for
the console to load a lot.

There are solutions proposed:
https://rails.lighthouseapp.com/projects/8994/tickets/3822-reload-doesnt-reload
https://github.com/rails/rails/commit/e6dffb70e6c1d524eeb5a40e1f8e01b067781143

And a seeming fix in edge:
https://github.com/rails/rails/blob/435bccda930e4dde3d0fafca958e1c8330b4c3ca/railties/lib/rails/console/app.rb

However, I have not had any luck with any of these patches or with the
new edge Reloader class. Has anyone? Am I missing some obvious
workaround or is there a reason I should not be using the console as
much?

Thank you for your help.
