[issue41544] multiprocessing.dummy.Process lacks daemon parameter

New submission from Martin : Although multiprocessing.Process has a `daemon` parameter, multiprocessing.dummy.Process doesn't. As multiprocessing.dummy is meant to replicate the API of multiprocessing and the daemon parameter is readily available in threading.Thread, it should also be

[issue41545] gc API requiring matching number of gc.disable - gc.enable calls

New submission from Yonatan Goldschmidt : I have a construct in my code where I wrap a function's logic with `gc.disable()` to prevent GC from triggering some race condition. Today this construct got a bit more complicated, and another function had to use this "trick". Now there are 2 flows:

Steven D'Aprano added the comment: Hi Seth, Surely you aren't relying on the behaviour that names in `__all__` *aren't* normalised but others are? Rather than a warning, I think the right solution here is to normalise the names in `__all__`. -- nosy: +steven.daprano
