Flaky timeouts in benchmarks.system_health.MobileMemorySystemHealth

Project Member Reported by erikc...@chromium.org, Oct 25

Issue description

In this build attempt:
https://ci.chromium.org/p/chromium/builders/luci.chromium.try/android-marshmallow-arm64-rel/114948

In 'with patch', Shard 14 flakily times out after 16 minutes:
https://chromium-swarm.appspot.com/task?id=40c069ac8e2f4210&refresh=10&show_raw=1

It looks like the task needed 24 minutes to complete [although the logs are so bloated that I can't even tell if it successful completed or was killed].

In 'retry without patch', Shard 11 flakily times out after 16 minutes:
https://chromium-swarm.appspot.com/task?id=40c0828a47d38710&refresh=10

The task took 23 minutes to complete.

In 'retry with patch', Shard 11 flakily times out after 16 minutes:
https://chromium-swarm.appspot.com/task?id=40c0b002c464b310&refresh=10&show_raw=1

The task took 17 minutes to complete.

In all cases, the last [meaningful] output in the task is 

"""
AssertionError: Failed: <class 'benchmarks.system_health.MobileMemorySystemHealth'>
Retrying failed tests (attempt #2 of 3)...
"""

Both of the shard-11 failures might be related to:
https://bugs.chromium.org/p/chromium/issues/detail?id=898844

Shard 14 failure does not have that same symptom.
