    I'm ok with this one, will merge it in my perf/core branch together with
    a fix for a bug I noticed in the original code and that remains with
    your changes: consider what happens if we do a second perf_evlist__mmap,
    we will call perf_evlist__id_add_fd again and thus bump evsel->ids++
    over nr_threads * nr_cpus, overflowing it.
