Dependency detection may be quite an expensive operation. What about a 
'positive' approach - deadlock detection on replica and, restart apply 
of a record that should be applied later? Have you thought about this 
way? What are the pros and cons here? Do you envision common cases where 
such a deadlock will be frequent?
