Comment 10 for bug 1217893

Seems the apparent working perf in the 14.04 release was an aberation. The 14.05 release [1] gives zero count for 'branches' value about half the time...

 Performance counter stats for 'ls':

                 0 context-switches # 0.000 M/sec
                 0 CPU-migrations # 0.000 M/sec
