Fixed accumulation of run time for processes that don't accumulate

Browse Source 
any statclock ticks.  Pretend that all the time up to the first
statclock tick is system time.  .  This makes a difference mainly for
benchmarks that test short-lived processes - the user and system
times for processes that each lived for about 1ms only added up to
about 10% of the real time even when there was very little interrupt
activity.

Break the printing of a quad_t variable correctly.
