And in the case this is still not clear ;) the inexact part is not only 
about formal inexactnes but about limited timer resolution as well. 
Despite the CPU clock ticking more than once each nanosecond the 
procesor and OS does not really count the time this accurately. On 
normal OSes I would expect microsecond accuracy at best (but that is a 
guess; I didn't measure).
