tab_switching.tough_energy_cases.reference timing out on Windows Zenbook Perf

Project Member Reported by martiniss@chromium.org, Dec 28 2016

Issue description

https://uberchromegw.corp.google.com/i/chromium.perf/builders/Win%20Zenbook%20Perf/builds/118 is an example build. Looks like an infrastructure issue; I don't know if a particular commit introduced this.

https://chromium-swarm.appspot.com/task?id=335ad4537c93c710&refresh=10&show_raw=1 is a run which times out. 

https://chromium-swarm.appspot.com/task?id=335ad458b863e410&refresh=10&show_raw=1 is a run which successfully completes.

I noticed that this log line appears when it completes successfully:
c:\b\s\w\irsfixqs\tools\perf\measurements\tab_switching.py:71: UserWarning: Function WaitFor is deprecated. It will no longer be supported on June 01, 2017. Please remove it or switch to an alternative before that time. telemetry.core.utils.WaitFor() is being deprecated. Please use catapult.common.py_utils.WaitFor() instead.

Could that be related? https://cs.chromium.org/chromium/src/tools/perf/measurements/tab_switching.py?q=tab_switching.py&sq=package:chromium&l=71 is the line in question.

Hmm, don't think it was caused by the deprecated thing. Although maybe...

Also, noticed something. The logs for the timed out test look like this:

INFO:root:Issuing command to ts_proxy_server: set rtt 0
INFO:root:Issuing command to ts_proxy_server: set inkbps 0 

Comparing these with a successful run, it's missing the following line:

INFO:root:Issuing command to ts_proxy_server: set outkbps 0

So maybe the ts_proxy_server is hanging? Not sure what that is exactly...
Stephen, can you disable the ref build for this test on Windows?
I'll disable the builds on windows :(

This also seems to be affecting the Win High-DPI bot. https://luci-milo.appspot.com/buildbot/chromium.perf/Win%2010%20High-DPI%20Perf/152 is an example build. Looks like it reliably fails there though.

This benchmark is unowned, poorly architected & disabled on almost every platform. Let turn this down.
