Comment(by moschny):

 Adding a `DeferredLock` that is acquired in `start_instance()` and
 released last in the deferred chain returned from `stop_instance()` solves
 the problem.

 However, it would be better to handle this in `AbstractLatentBuildSlave`
 would be much better, so all heirs benefit.

 Will have a look on how to do that soon.
