Metrics on Windows XP

Hi John,

Thank you very much for sharing your source code with the community.

About metrics, we have been working on getting counters from windows XP, but
actually not the ones you need. I have just checked if it was easy to get
the CPU load average, but as you mentionned, it is all based on %, not on an
average number of idle or waiting processes.
As we start to work on Vista, I will have a look at it and tell you if I see
an easy way of getting some extra info.

About the new code you shared, I've compiled the quo, qrs and qos module,
then the util module, but I still have a runtime problem integrating it by
hand with my 12.2 stable version. Is there any special configuration to make
to solve this
"Caused by: java.lang.VerifyError: Cannot inherit from final class
        at java.lang.ClassLoader.defineClass1(Native Method)
"?

Cheers,
Guillaume
