That works, so I can see that there are 77949 lines in the xenstore when
the domid counter is up to 3050. In comparison, a dom0 where the domid
counter is up to 868 only has 1688 lines. Based on that very limited
measurement, the rate of growth does not appear to be linear...

The performance is definitely getting worse and worse the higher domid
gets.
