Started bisect job https://chromeperf.appspot.com/buildbucket_job_status/9001540479746208832

Bisect failed: http://build.chromium.org/p/tryserver.chromium.perf/builders/winx64nvidia_perf_bisect/builds/1865
Failure reason: the build has failed due to infrastructure failure.

Temporarily declaring bankruptcy on the *desktop* system health benchmark.
The number of alerts became unmanageable and the overall process needs to be improved to make it sustainable.
The alerts have been turned off and I'm archiving the outstanding regressions.
Note: this is just about desktop, the mobile system health stays up.
