Re: 'perf stat --repeat N' oddity/regression

So it appears it broke somewhere between v4.0 and v4.1, as the v4.0 install 
displays:

    16,244,802,268      instructions               ( +- 23.01% )

       2.108676769 seconds time elapsed                                         
 ( +-  0.86% )


[a few minutes later]

Bisected it down to:

     perf stat: Introduce read_counters function

So this look like to be a regression.

Thanks,
