Swarm, for example, has a logical model of concurrency and options for 
controlling it.   Suppose two agents schedule two events in the future 
that happen to be at the same time to the time resolution of the 
model.   When these events are run, they can either be iterated in 
serial or in randomized order.  Randomized order simulates the 
non-determinism one would expect from a truly asynchronous (parallel) 
realization of the model.   You can indeed get artifacts / apparent 
causation in models depending on the details of event ordering...
