hi,
this one seems to break 'perf stat -r X' not sure why so far..

final counts seems to be accumulated instead of displaying average, like:


with this patch:

	 Performance counter stats for './test_progs -n 103/1' (2 runs):

	       206,815,929      cycles:u                                                             ( +-  0.05% )
	    16,052,747,533      cycles:k                                                             ( +-  0.10% )
	    16,259,643,167      cycles                                                               ( +-  0.10% )

		   1.98093 +- 0.00586 seconds time elapsed  ( +-  0.30% )


without this patch:

	 Performance counter stats for './test_progs -n 103/1' (2 runs):

	       103,300,812      cycles:u                                                             ( +-  0.37% )
	     8,016,856,866      cycles:k                                                             ( +-  0.32% )
	     8,120,200,572      cycles                                                               ( +-  0.32% )

		   1.97272 +- 0.00270 seconds time elapsed  ( +-  0.14% )


any idea? ;-)

thanks,
