The chromium.chromiumos Linux builder has timed out in telemetry_perf_unittests in 4 of the last 8 runs:

https://build.chromium.org/p/chromium.chromiumos/builders/Linux%20ChromiumOS%20Tests%20%281%29

The timeout is always in benchmarks.system_health_smoke_test.SystemHealthBenchmarkSmokeTest.system_health.memory_desktop.browse_accessibility:tools:gmail_compose.

Per the comment at issue 725516#23 I am opening a separate bug for this builder. Ned, are you the right owner?

Outut from example failure: https://chromium-swarm.appspot.com/task?id=38d97cb0de0ed310&refresh=10&show_raw=1
