Should changes to spec_helper/rails_helper be picked up automatically?

[andyw8]

Should it be necessary to configure Spring with

Spring.watch "spec/spec_helper.rb"
Spring.watch "spec/rails_helper.rb"

or should it restart automatically if these are changed?

I'm trying to work out if it's a problem with my setup, or if that's the intentional behaviour. If this isn't the default behaviour, then I'm curious to know why.
