Hi Wayne-

I can't get Linux to crash for this bug but I do see some memory access 
grinding when I follow your steps.

Can you test the attached patch and see if it fixes the issue for you?  
Launchpad is down right now, so I can't attach it to the bug report.

This patch should not be committed to the tree.  If it fixes the issue, 
we can address the root cause but that's a bigger job.

-Seth
