Whilst it seemed to help in some cases, I'm not keen to merge it until we've identified a sensible way to parameterise the threshold and also explain why it doens't appear to help at all on some platforms. I guess I could respin a version that takes the threshold on the cmdline and also checks to see that the event stream is enabled, since that might help with further benchmarking. Would that be useful? Will
