[issue33240] shutil.rmtree fails if inner folder is open in Windows Explorer

Gregory P. Smith added the comment: oh, I missed that a notification happens to the other process(es) in a common case, a bit of retrying with backoff would actually make sense there. But I wouldn't let a retry run for longer than a second or three, as code tends to assume that rmtree is pr

Ben Buchwald added the comment: Hopefully I'm not too late to comment on this. I also just hit this issue, but I do not agree with the proposed PR. Only modifying _GatheringFuture.cancelled() just fixes one of the side-effects of the problem. The state of the future is still FINISHED and not

New submission from Chad Netzer : In Python v3.9+ there was a regression in the amount of used memory for list-literals, due to switching to using list_extend() to allocate memory for the new list to accomodate the literal elements. Example, in Python v3.8.x (and before): ``` $ python38 Python
