Comment 2 for bug 322002

Even that the respective IOStream::File object for the unfinished file seems properly destroyed after the error, somehow a file handle leak happens here. With every download retry (and fail because still 'Not enough space in the disk') another RW file handle stays open for the unfinished file.
