When I run two 100% CPU loaded processes, the machine gradually gets slower and
slower, until eventually it limps along at 500-ish MHz rates.
Killing powerd and starting it again seems to bring the machine back to full
speed (for some time).
Looking at the powerd -v output, my gut feeling is that powerd sometimes looses
track of what the (current) top frequency is and thus gradually drags the
machine slower or slower...
I have had a faint feeling for some time that this machine runs significantly
faster after a reboot, but I have no observations to support that.

Never attribute to malice what can adequately be explained by incompetence.
