The hobbit monitor system uses your routine to gathers cpu load. But it ALWAYS showed 100% in my case: windows with 64 bits architecture running a XP virtual machine (32bits). In this machine the code is compiled and executed.

The solution I applied was: Add "WIN32" to the options in de preprocessor definitions. Then, just like magic, it worked.

That worked for me. Anyone have something to add?
