> Gridmix STRESS mode can be improved as follows:
> 1. The sleep time in JobMonitor can be reduced and/or made configurable
> 2. Map and reduce load calculation in StressJobFactory can be done in one loop
> 3. Updating the overload status from the job submitter thread (inline)
> 4. Optimizations to avoid un-necessary progress check (which inturn would result into
delay)
