Our xen-thrash testsuite was running. It was configured to boot:
* 5 domUs swap thrashing (eatmem.c)
* 5 domUs that busy-loop CPU
* 5 domUs running crashme w/ 2.6.18 kernel
* 5 domUs running crashme w/ pv_ops kernel
* 5 domUs in a boot up -> sleep 60 -> shut down loop
* 5 domUs in a boot up -> sleep 60 -> xm destroy loop
We kicked off this identical run on 10 hosts. On another host I cranked these
numbers up to total about 80 domUs. They're all still running fine.
The one that hit this BUG is still up, if any Hypervisor output would be
helpful.
