That is just my laziness.  :-)  It is such a small program that 16
passes goes by quickly and I didn't want to spend time looking for the
optimal number of passes.  I also accidentally forgot the unsafe
options that I tried to see how much speedup they would give.   ...I
did some more testing and it seems that the program doesn't change
much after 4 passes.  However, there are differences between 1, 2, 3,
and 4 passes.
