In the particular case I was interested in here, the test script thought
everything was successful :-(.  I'm working on fixing that little problem,
but I do not believe that the TAP scripts are so bulletproof that there
will never be a need to override their judgment.

Yeah, that's a reasonable design.  There doesn't seem to be a good reason
to randomize the test directory names.
