Not really no as you have no guarantees where a Task pauses (AFAIK). It might be that in practice you will avoid some race conditions (e.g. if the compiler never inserts a yield into something like array[i] += value making it practically an atomic operation). But I’d never want to rely on this! Julia has no way of controlling the yield points so you always had to guess where they are and hope - which is not how I would want to construct my programs
