I just realized what you did.. you set enterCritical and leaveCritical on
constructor...
I asked you a simple question... why there's no MIN_VALUE as you said you
would do... then you started answering something else.. and tell me you don't
have time??? ;)

> To compute timeouts of the CriticalAnalyzer Instead of
> System::currentTimeMillis is preferrable to use System::nanoTime, that is not
> sensible to OS changes on the system clock (eg NTP compensation).
