That unsymmetric??? Interesting... Of course this saves you the
headache of explicitely round-robin.

I'm still worried about the "normal" kind of machines with more
symmetric node-distances. TX-7 for example has

10 15 15 15 20 20 20 20
15 10 15 15 20 20 20 20
15 15 10 15 20 20 20 20
15 15 15 10 20 20 20 20
20 20 20 20 10 15 15 15
20 20 20 20 15 10 15 15
20 20 20 20 15 15 10 15
20 20 20 20 15 15 15 10

I'm fine with sorting if we get some sort of round-robin at least over
the first off-diagonal node level. But the code I've sent you was the
best idea I had (in the limited time I could spend for this...).
