One of the big cpu time consumers when running xfsqa on UML is forking of new processes. when looping lots of times, using 'expr' to calculate the loop counter increment means we fork at least once every loop. using shell builtins means that we don't fork and many tests run substantially faster. Some tests are even runnable with this modification. e.g. 110 went from taking 4500s to run down to 9s with the loop iterators changed to avoid forking.
