Sounds about right :)

Absolutely.  I will run it today and post my findings.  It would be
great if others "out there" could do the same to help verify that the
problem is better or fixed.  Since threads are involved, many tests
across varying platforms will be more convincing :)

That is excellent news.  The latest version generates an XML file of
results that it automatically submits to us for review.  It would be
great if you could use that as your data source for merging the data
into your own test infrastructure.
