Coroutines achieve very similar things to threads, but avoid problems resulting from the pre-emptive nature of threads. Specifically, a coroutine indicates where it will yield to the other coroutine. This avoids lots of problems related to synchronization. Also the lightweight aspect is apparently important for some simulations when they have many thousands of agents to simulate--this number of threads becomes a problem.
