 If -n is not given, a suitable number of loops is calculated by trying
 successive powers of 10 until the total time is at least 0.2 seconds.
 
-The difference in default timer function is because on Windows,
-clock() has microsecond granularity but time()'s granularity is 1/60th
-of a second; on Unix, clock() has 1/100th of a second granularity and
-time() is much more precise.  On either platform, the default timer
-functions measure wall clock time, not the CPU time.  This means that
-other processes running on the same computer may interfere with the
-timing.  The best thing to do when accurate timing is necessary is to
-repeat the timing a few times and use the best time.  The -r option is
-good for this; the default of 3 repetitions is probably enough in most
-cases.  On Unix, you can use clock() to measure CPU time.

 Note: there is a certain baseline overhead associated with executing a
-pass statement.  The code here doesn't try to hide it, but you should
-be aware of it.  The baseline overhead can be measured by invoking the
-program without arguments.

-The baseline overhead differs between Python versions!  Also, to
