I don't have a problem with this, but in my testing using original-awk, 
mawk, and gawk, both methods had similar distributions when choosing 
random numbers between 1 and 5. Interestingly, mawk was about twice as 
fast as gawk, which was about twice as fast as original-awk in this 
(mostly useless) test.
