That issue actually doesn't happen with regular elixir, since it's immutable and stateless, the scheduler doesn't wait for the process to voluntarily wield (it's always safe to switch, so it just gives some fixed time for each process, which makes it very low latency and very reliable but not very efficient at any individual task due to all the switching). Calling other languages from erlang/elixir create dirty processes that can't be scheduled this way and may cause those issues.

Since I didn't use dirty processes in elixir it did make me forget about this obvious issue you pointed out, that for a mutable language like Julia can happen in every thread, but that's not something that limits the expressiveness of the model, but something that requires consideration to avoid while programming and language level mechanisms to protect the thread (at the very least the ability to define timeouts that can throw an exception on any spawned process) or maybe a future framework on top of it that handles this in a safer way (something like Akka). I can only hope Julia can achieve the full potential of it's multithreading model.
