When extracting with tarfile, reading stops at the end-of-archive marker, which can leave the end of the compressed stream unread. For gzip, that means its CRC never gets checked, so a corrupted archive whose deflate data still decodes would extract without error. Read the decompressed stream to the end after extracting, like the tar pipe already does. This made test_stream_extract_broken_archive_not_retried[gz] fail intermittently on Windows.
