I continue thinking that the origin of the issue has to do with tqdm (and not with Arrow): this issue only arises for version 4.50.0 (and later) of tqdm, not for previous versions of tqdm. My guess is that tqdm made a change from version 4.50.0 that does not properly release the iterable. |

In 42320a1 we added a call to gc.collect to resolve some issues on windows (see #2482)
However calling gc.collect too often causes significant slow downs (the CI run time doubled).
So I just moved the gc.collect call to the exact place where it's actually needed: when post-processing a dataset
