So, this is the line that is messing up your specs. Since logger is a class variable, it does not get torn down like the other stubs and stays around for others with bleed.

if you add the following on the top-level of the spec file:

```ruby
describe Crichton do
  before do
    Crichton.clear_registry
    Crichton.clear_config
  end

  after(:each) do
    Crichton::logger = nil
  end

  # ...
```

You should be fine.
