Apparently my cancel didn't get through.  After posting my message, I realized
that your argument was 2**n instead of n.  The argument of my programs is the
exponent.  BTW, if you send the value 'i' from your patch of code to my
program, everything works fine.  My apologies for the mixup.  I'm going to
find my article and try to kill it again.
