Tetsuo Kiso ea3bfb5d4c Delete assertions to check elapsed CPU time.
The accuracy of getrusage() is limited by the resolution
of software clock as described in
http://www.kernel.org/doc/man-pages/online/pages/man7/time.7.html

The assertions required a timer with microsecond accuracy.
However, we don't necessarily want the timer, and we don't
want to add some time-consuming processes to the test code because
we normally build programs again and again, which means
we want to run unit tests as quickly as possible.
