Subject: [PATCH] preserve threading details in benchmark eventlogs

We need the log of threading operations so that eventlog-to-tracy can
produe a valid trace. Without it, eventlog-to-tracy will generate an
invalid trace where all the spans are impossibly on the same thread and
tracy may/will crash
