Yes yes I saw the answer, but now I was thinking that what I need is
simply this:
tar czpvf - /path/to/archive | split -d -b 100M - tardisk

since it should run only on Linux it's probably way easier, my script
will then only need to create the list of files to tar..

The only doubt is if this is more or less reliably then doing it in
Python, when can this fail with some bad broken pipe?
(the filesystem is not very good as I said and it's mounted with NFS)
