I've tried spring with Ruby 1.9.3/p327 (installed via rvm), running Rails 2.3.6.

* The server starts up twice (I had killed all instances before):

Maybe these are for test and dev env. But I've already seen three server.rb instances so I doubt that.

* An exception is raised when doing 'spring rspec' for the first time:

* Running 'spring rspec' the second time it works, but tests fail (they don't fail when being run with plain rspec):

> spring rspec spec/models/content_spec.rb 

[...]
  19) Content#portfolio_item returns nil when content not in portfolio
     Failure/Error: let(:image) { FactoryGirl.create(:image, user: user) }
     ActiveRecord::RecordInvalid:
       Gültigkeitsprüfung ist fehlgeschlagen: User ist nicht gültig
     # ./spec/models/content_spec.rb:273:in `block (3 levels) in <top (required)>'
     # ./spec/models/content_spec.rb:281:in `block (3 levels) in <top (required)>'
     # <internal:prelude>:10:in `synchronize'

I think this has to do with complex factories and database cleaning (Database Cleaner) needing some adaptions for spring, didn't investigate further so far. These tests pass with spork and zeus, though. 


* (minor) just running "spring" (as I'm used to with "spork") could output a more useful message:

This happens even with the simplest rake task (which has no Rails dependency), so it doesn't seem to be a rake routes specific problem.

Hope this helps.
