AcmeCheck() is an instance's method that can be triggered from three distinct goroutines. Although it doesn't change the model, it reads it and can lead to inconsistent data or even a race in the map of acme related data if called concurrently with a model update. This commit prevents that AcmeCheck() is called during instance's model updates.
