Bisect failed: http://build.chromium.org/p/tryserver.chromium.perf/builders/android_s5_perf_bisect/builds/1102
Failure reason: the build has failed due to infrastructure failure.

Status: WontFix (was: Untriaged)
Might be a false alert the metric is somewhat noisy, and it appears to have reverted to the mean.
