Without this patch, a lot of them fail with error messages like

    _pickle.PicklingError: Can't pickle local object <function test_column_projection_map_partitions.<locals>.myfunc at 0x7fff7517b8a0

and one test fails with

    dask.multiprocessing.TypeError: cannot pickle 'itertools.chain' object

```shell
git grep -l -e 'versionCheckProgramArg = "--version";' -e 'versionCheckProgramArg = \[ "--version" \];' | while read f; do
  sed -i '/versionCheckProgramArg/d' "$f"
  sed -i '/^$/N;/\n$/D' "$f"
done
```
