> FileWriter and StreamWriter call `self.finish().unwrap()` in their `Drop`
> implementations if the write has not already been finished. However, a common
> reason for the write to not be finished is an earlier IO error on the
> underlying stream. In that case, the destructor will panic, which is not
> desired.
