I will say that the NSLog was done for this particular example, just
to see what's going on.
The loop otherwise keeps rolling along, with or without an NSLog, %d
or %u.
Going without an NSLog is how I initially found out about this issue,
in that my program would run into other problems related to this loop
going past its bounds.

The correct type modifier for unsigned integers is %u not %d. Switch
it and try again to see what's really happening.
