A nice extension of this is to use exponentially distributed delays. Then reoccurring events form poisson processes which are really easy to reason about when composed eg if you have N servers firing off events at the same exponentially distributed rate the times are distributed the same as if you had one server firing events at N x the rate and distributing jobs uniformly at random to the other servers.
