    @class Win360::Win360Timer
    
    Win32/Xbox360 implementation of the Time::Timer class. Uses 
    the QueryPerformanceCounter() functions.

    @todo solve multiprocessor issues of QueryPerformanceCounter()
    (different processors may return different PerformanceFrequency
    values, thus, threads should be prevented from switching between
    processors with thread affinities).
