As per Stefan Hajnoczi: "This command is only available from the human monitor. It's not very useful because it historically hasn't been able to pretty-print events or show them in the right order (we use a ringbuffer but it prints them out from index 0). Therefore, I don't think we're under any obligation to keep this command around. No one has complained about it's limitations - I think this is a sign that no one has used it. I'd be okay with a patch that removes it."
