In fact, XenServer has a patch that will automatically adjust dom0's
weight based on the weight of other VMs running on the system, in an
attempt to make sure dom0 can get enough cpu time.

I haven't submitted it to the list, because I don't think it's really
appropriate for the open-source tree.  But I'll dig it out and post it
as an RFC; even if it's not ultimately accepted, it might not be bad
to have the patch floating around.
