But what do you do if the percentages don't add up to 100%?
We'll probably have another setting CPUBudget= where you can specify a
floating point value that specifies the maximum number of CPUs a cgroup
can get as hard ceiling. i.e. you could specify CPUBudget=0.33 to grant
a cgroup only 1/3 of one CPU at max. Or CPUBudget=3 to grant a cgroup
access to full 3 CPUs of CPU time.
