> Python: pyarrow.parquet.write_to_dataset creates cyclic references

> See https://github.com/apache/arrow/issues/1285 for the initial issue. Having
> cyclic references is a valid state in Python as they can be cleaned up by the
> garbage collector. But as the garbage collector normally runs at a point
> which is not clear to the user and we deal here normally with larger objects,
> we should get rid of the cyclic reference to evict data as soon as possible
> from main memory.
