This is a good suggestion, I think.  Much better than mine in my other
email.

In an automatic test system the logfiles won't get big enough to be
rotated.  In a manual setup this is just a "random hazard" which you
seem to be prepared to accept...

But: it is easy for the runner to see if the logfile was rotated.  It
can open the logfile a second time and check if it has the same inum.
