/**
* A type of stateful objects whose state is guaranteed to be recoverable. The
* logging is done based on PreEnter events. The guarantee offered is the
* following: IF a recoverable state is reached by the instance, then its image
* is GUARANTEED to be recoverable. The inverse does NOT hold: the fact that an
* object is recovered in some state does NOT mean that the state was reached.
* Indeed, other PreEnter listeners may still have prevented the transition in
* the last moment. However, this should not be a real problem; applications
* should take this into account.
