Using the HLT instruction to stop the processor when idle isn't something
done by a program, but is instead a feature of the operating system.
Windows NT and Linux does this, I think Win95 does as well, Windows 3 and
DOS do not.
Since the purpose of Prime95 is to use as much of the CPU time as can be
spared by other processes, it works extremely bad with the concept of
saving power by halting the processor, because the optimal working
conditions for Prime95 is to run flat out using the entier processor all
the time.
