This patch provides a workaround for bugzilla #90 which shows up far too

often when creating and then destroying lots of domUs and dom0 is SMP.
Details are in the [1]bug.  With this patch, I now can create/destroy
domains in a tight loop for hours where previously every 3 to 10 cycles
would blow up.
