Hi Frank

Ok, no more posting from me after winning a bottle of whiskey at the Irish 
Pub on quiz night. :)

I've been looking at this one, and I'm not sure about it.
According to the help output, 

"-v       --verbose         output values on stdout for statistics
                           format: n:c:v n=tasknum c=count v=value in us"

./cyclictest --verbose -p99 -t | awk '$2~/^0/{ print }' 

       0:       0:       0
       1:       0:       0
       2:       0:       0
       3:       0:       0
       4:       0:       0
       5:       0:       0
       6:       0:       0
       7:       0:       0

So, it looks like the values are 0 at count 0, doesn't that make sense?

Thanks
