[New-bugs-announce] [issue39609] Set the thread_name_prefix for asyncio's default executor ThreadPoolExecutor

[Markus Mohrhard]

New submission from Markus Mohrhard <markusm at dug.com>:

The ThreadPoolExecutor in BaseEventLoop.run_in_executor should set a thread_name_prefix to simplify debugging.

Might also be worth to limit the number of max threads. On our 256 core machines we sometimes get 1000+ threads due to the cpu_count() * 5 default limit.
