Our view has always been that dom0 is primarily a service domain. If 
that isn't the case then you may want to reduce its guarantee (easily 
done) but bear in mind that this can have a bad effect on domU I/O 
performance. Hopefully my patch gives a balance that strongly favours 
dom0 but not so much that other domains get starved for significant 
periods.
