+ On the use of __debug__: this is a built-in variable, set to True
+ normally and to False when Python is invoked with -O.  I use this to
+ produce verbose output without -O but minimal output with it.  For the
+ actual benchmark, Python should use -O, and Dan can simply set
+ __debug__ to False in the builtins if he prefers.
+ 
+ On timing: there's a requirement that the benchmark runs for at least
+ 30 seconds.  It currently runs for nearly a minute on my home box,
+ which is a four-year-old 650 MHz Pentium box.  If the contest hardware
+ is so fast that it runs under a minute, there's a number in b.py that
+ can be cranked up to increase the number of runs.
