[Feature Request] Investigate asyncio.as_completed and asyncio.wait usage of `set` as non-deterministic

[cretz]

Describe the solution you'd like

asyncio.as_completed and asyncio.wait may be non-deterministic in their use of set. See https://github.com/python/cpython/blob/v3.12.3/Lib/asyncio/tasks.py#L609 and https://github.com/python/cpython/blob/v3.12.3/Lib/asyncio/tasks.py#L458. See if anything can be done and if not, document that they are dangerous and warn on their use. May need to provide deterministic alternatives.
