Move blocking things to own thread

Blocking calls can be sent to a thread for execution whilst offering an asyncio interface to deal with

Warning

Note however, that there is no way to automagically interrupt the function executed in the thread, if it’s not designed that way.

So cancelling this task is technically possible, but without any effect.

import asyncio
import time

task = asyncio.create_task(
    asyncio.to_thread(blocking_wait_for, 1)  # creates coroutine
)
await task
print(task.result())

Done waiting for 1 seconds.
