I noticed this when testing out Cubes - specifically the the Slicer server.

I was running in Python 3.8.1 and noticed that CSVs had many null bytes - lots of them. This was causing all types of problems when loading and parsing these CSV. Upon tracking down the issue I noticed this was the result of calling `truncate on a StringIO stream.

Specifically the docs state:

"Changed in version 3.5: Windows will now zero-fill files when extending."
