So do I. If anybody figures out how to compute this aggregate time in a way that doesn't itself significantly impact the performance of Sage, I'd love to add this feature to the output of "time". So far, nobody has figured out how to do this and explained it to any of us. Here "this" is basically "figuring out the total CPU time used by a group of unix processes."
