Can you comment on whether the differences between StringIO and io.StringIO might be significant? https://stackoverflow.com/a/49795277

Move it to the import list at the top of the file.

This and the following cases want byte IO, don't they?

StringIO is obsoleted in python3, replaced by io.StringIO.
Yet io.StringIO only handles unicode string, while StringIO.StringIO only handles str, i.e. bytes.

Yeah, it's probably safer. It really depends on the content of `e`. It also appears that Python 2.7 supports io.BytesIO, so I'd rather use that uniformly.

Use BytesIO as a repalcement... it more closely matches StringIO.StringIO

Update StringIO conversion after more testing.

With Python 2 this fails with:
TypeError: unicode argument expected, got 'str'

Why is this necessary? send_string returns a BytesIO object so why create a different one?
