I noticed lately that even with
n_jobs=None(which should really be equivalent ton_jobs=1) I would see parallel stuff in logging:This PR fixes the logic such that when
n_jobs=Noneends up being equivalent ton_jobs=1and usinglistdirectly instead of anyParallelstuff for the actual execution.EDIT: Think we don't need a changelog entry since it's just a minor logging change at the end of the day.
