Looks like there might already be a problem using evsel->threads instead of evlist->threads with the logic relating to evsel->system_wide getting lost - but that happened already in "perf evlist: Factor perf_evlist__(enable|disable) functions". Probably the threads should not be propagated in that case, but it needs more investigation. I will try to look at it today.
