 This work stalled at some point.  While sysutils/estd works fine for most
 use cases, it is unclear whether the functionality should be implemented in
 the kernel, i.e.  by extending cpufreq(9). Some benchmarks are needed.
 
 It should be also discussed what the use cases and the desirable behavior
 are for huge systems with tens of CPUs; e.g. should it be possible to
 control the frequencies via cpuctl(8)? For instance, in some cases, it might
 be useful to set heavy-hitting CPUs to the maximum frequency while lowering
 the frequencies in other CPUs.
