RDTSC is rather flawed in multi-core systems (see http://msdn.microsoft.com/en-us/library/bb173458(VS.85).aspx for some info on that).
What would be really nice is a system independent high-resolution timer that works when the thread in question gets switched between multiple CPUs with power saving.
The problem with such a timer, of course, is that it would be much more expensive to call.
