The "(included in ther second result)" should be "(included in the
first result)". In other words, the CPU-time report includes time spent
on GC.

(Of course, on a uniprocessor, all of the CPU time is also included in
the "real" time, though the granularity of CPU measurement is typically
less than the real-time granularity.)
