Argh! I mis-typed. It is not dump files from the same host that are
slow. Instead, it is always the tape writes of backups of the same
disk list entries that are slow.

In the report, see that some borneo tape writes were fast, but one
is much slower. So why is that particluar one *always* slow? It
should be just a mindless tape dump, right?
