Actually, I have a test case.  I just sent it out to Tom a couple of hours ago. 
The quick and dirty is that it shows the problem after running for about 20
minutes on my Xenon system with 8.1.0...  I cannot get it to fail on my AMD
system with a much higher load...

I can send it to others who are interested.  The e-mail with dump, module and
script is just over 1Mb.

Cheers,
Rob
