Ah, ha!  This appears to work.  I didn't need to reserve a CPU for the 
dom0 (knock on wood).  Much obliged, Luke.

I'm academically curious, though - I seem to have created a CPU deadlock 
of some sort, yet in 'xm top' none of the CPU's were pegged.  I've got 
no reason to not give dom0 utmost priority - that makes perfect sense to 
me - but I'm surprised the Xen scheduler would allow me to get into this 
situation by default.
