How would you do parallel processing with `Flow` ?
1. Map T to a `Deferred&lt;R&gt;`, then await each ?
2. Use plain coroutines with channels ?

Wouldn't it makes more sense to pass a `CoroutineDispatcher` instead of an `ExecutorService`, since we are dealing with flows, then `launch` coroutines instead of submiting tasks ?

Than create a suspend function that takes a user and returns a Map&lt;User, Address &gt;
