> One issue with using {{Table.to_pandas}} is that it results in a memory
> doubling (at least, more if there are a lot of Python objects created). It
> would be useful if there was an option to destroy the {{arrow::Column}}
> references once they've been transferred into the target data frame. This
> would render the {{pyarrow.Table}} object useless afterward
