When `BLI_task_parallel_mempool` does not use threading, the `userdata_chunk` is allocated locally simulating a TLS. However `func_reduce` is not called so the original chunk is ignored. `task_parallel_iterator_no_threads` is another function that doesn't call `func_reduce`. It also ignores `userdata_chunk_local` in the main iterator. The solution in these cases is not to create a `userdata_chunk_local`.
