Hmm. I wonder if it might be time to find a way to be able to optionally split the qemu_log output on a per-cpu basis. It wouldn't necessarily always be helpful, because we'd still have the case of a given TB being translated by one cpu and executed on another, but it could make some things easier to follow. r~
