trying to install corefoundationasyncio on python3.11 with pip22.3 triggers the following warning:

DEPRECATION: corefoundationasyncio is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at pypa/pip#8559

the warning points to the following discussion: pypa/pip#8559

Hi!

First let me say a huge thank you for sharing corefoundationasyncio: I had been looking for a way to use asyncio in PyObjC-based Cocoa apps for a while and this is gold. It's working really well for me.

I have an issue with using concurrent.futures.ProcessPoolExecutor, that I use with loop.run_in_executor(). It's mostly working just fine, but in some situations that I haven't quite pinned down yet (but seem repeatable), a sub-process will fail like this: concurrent.futures.process.BrokenProcessPool: A process in the process pool was terminated abruptly while the future was running or pending.

Now, I read your note about the selector implementation, and how it's not compatible with a GUI app. I know concurrent.futures.ProcessPoolExecutor uses the selector module, so I was wondering (without understanding much about the subject in general, I should add) if that may be hinting at the root of my problem. Should I perhaps avoid concurrent.futures.ProcessPoolExecutor and solve my multi-processing needs some other ways, perhaps with the subprocess module?

Thanks for any clues, and thanks again for bringing asyncio to Cocoa!
