I also added this for the casual reader to get up to speed more quickly,

When we use -c or a period=N term in the event definition, then we don't
need to ask the kernel, via perf_event_attr.sample_type |=
PERF_SAMPLE_PERIOD, to put the event period in each sample, as we know
it already, it is in perf_event_attr.sample_period.
