Hi Chris, Thanks for the response. This looks helpful.
I need to develop up a benchmark (or set of benchmarks) which is completely self contained and does not use the gui. I fully realize the value (from the standpoint of realism) of driving a gui with a load driver. However, the objectives of the DaCapo suite are rather different (realism is one of many dimensions we hold in tension). Anyway, I will persevere with trying to get something working which does not depend on the gui.
