Another thing the test harness needs is the ability to set a limit on the memory size of gdb. It's a safety net because sometimes changes happen that cause memory usage to really swell and we don't want to drag a machine into thrashing just to get through the test. Using system monitored settings for both cpu and memory usage would be good (ulimit).
