Also on the topic of limitedParallelism, using Loom for everything and therefore not having to mix Dispatchers.Default and <http://Dispatchers.IO|Dispatchers.IO> probably also prevents all thread switching when switching to a context using limitedParallelism? Because you never run into a case where you have to switch from a thread in the Default thread pool into a thread in the IO thread pool or vice versa
