I noticed that in 3.7 a lot of high level functions have been added to the asyncio API, but nothing to start blocking functions as non-blocking threads. You still have to call get_event_loop() then await loop.run_in_executor(None, callable).
Would an API like this make sense?
async def run_thread(callable, *args, *, loop=None, executor=None, timeout=None)
Then it could just be used like this:
await asyncio.run_thread(my_blocking_read, 4096, timeout=10)
This API could wrap the run_in_executor in an asyncio.Task, that way you wouldn't have to await it to start the thread. There's evidence that this has confused people in the past:
