Just for the record: r.viewshed run 36 hours on a 2 years old machine to calculate the viewshed on this region of 1.6Gigapixels. Peak swap file size: 216GB, the stream_dir directory for swapping was mounted over NFS, hence a bit slower than a local device. So we only need to solve the number of files' limit in Windows' mktemp().
