I don't think people do because they are so noisy.  Solving the problem
was the primary motivation of my pile of test update script
enhancements.

+1.  I don't believe there's a silver bullet here.  Different tools are
appropriate for different kinds of tests.  I happen to think Michael's
proposal is another useful tool in the box, as is Hal's.
