Reload an initializer file on every request in Rails.

reloader.rb

# add this into application.rb
initializer_file = Rails.root.join('config', 'initializers', 'my_initializer.rb')
reloader = ActiveSupport::FileUpdateChecker.new([initializer_file]) do
  load initializer_file
end
ActiveSupport::Reloader.to_prepare do
  reloader.execute
end

to work this reload_classes_only_on_change should be false

/config/environments/development.rb
config.reload_classes_only_on_change = false

Is this needed for initializers only (purpose of this gist)?
