Thanks a lot.  It started downloading  with no freeze so far, and -c 
made it append to the incomplete *.iso file already downloaded.
At this time it predicts 13h 44m to download. I can absolutely live with 
that.
If I experience another freeze, I just restart the whole thing with the 
-c option.
I would be surprised if it does not freeze at some time.

This freeze problem seems to be quite a rare thing, I have not seen many 
others having the same problem, ant it is a very elusive problem.
Is it software related?
Is it hardware/software related?
Why has the effect changed? Earlier I could enter the PC via an ssh back 
door (from my backup machine) and shut down Xorg. That did the trick. 
But now the freeze condition has become more serious, now it shuts down 
the ethernet card as well so that the backup PC no longer is connected.
I will study the thread about ssh here first, but I also have 
experienced that the backup machine no longer can run X via ssh to the 
main PC.
ssh -X 10.0.0.6 goes fine, but starting kwrite, gftp or any other 
GUI-based program fails.
Before the present calamities started, I actually run the main PC via 
the backup PC, a happy symbiosis which gave me time to focus on 
productive programming.
