multithreading. The only thing it prevents is full use of multi-CPU resources in
a single process. But if you are using threads to reduce latencies rather than
increase throughput, the GIL isn't really an obstacle (it probably makes things
a bit worse than a free-threading scenario, but not that much; and you can tweak
