Annotated Snippet

ToDos sorted by priority:

- Use bitmask functions to parse CPU topology more robust
  (current implementation has issues on AMD)
- Try to read out boost states and frequencies on Intel
- Somewhere saw the ability to read power consumption of
  RAM from HW on Intel SandyBridge -> another monitor?
- Add another c1e debug idle monitor
  -> Is by design racy with BIOS, but could be added
     with a --force option and some "be careful" messages
- Add cpu_start()/cpu_stop() callbacks for monitor
  -> This is to move the per_cpu logic from inside the
     monitor to outside it. This can be given higher
     priority in fork_it.
- Fork as many processes as there are CPUs in case the
  per_cpu_schedule flag is set.
  -> Bind forked process to each cpu.
  -> Execute start measures via the forked processes on
     each cpu.
  -> Run test executable in a forked process.
  -> Execute stop measures via the forked processes on
     each cpu.
  This would be ideal as it will not introduce noise in the
  tested executable.
