This has been flaky for a while now so it's hard to identify the culprit: https://build.chromium.org/p/chromium.perf/builders/Mac%20HDD%20Perf%20%281%29?numbuilds=200

(Looks like there's no owner listed for this benchmark, so I guessed jeremy@)
 
I'll disable the test on mac reference builds: https://codereview.chromium.org/1989153004/

I re-enabled this benchmark and it no longer appears to be flaky on mac. If it starts failing again, a new bug should be opened and the stories disabled.
