WebRtcDataChannelTest.DataChannelGC flaky

Project Member Reported by guidou@chromium.org, Jun 1 2016 
See https://build.chromium.org/p/chromium.win/builders/Win7%20Tests%20%28dbg%29%281%29/builds/49227

Not clear why it became flaky, but it also became flaky on Android ASAN a few weeks ago.

In the meantime, disabling the test.

Although tests aren't tied to releases, I'm adding the M53 label so this doesn't fall into a black hole. :)

Status: WontFix (was: Assigned)
It looks like flakiness has stopped. Probably due to fixes in GC.

This is blocking the CQ

Could https://codereview.chromium.org/2531973002 ("Simple BlinkGC heap compaction.") be related?

Comment 11 by sigbjo...@opera.com, Dec 12 2016 

I don't know what that build log refers to, but

 https://build.chromium.org/p/tryserver.chromium.android/builders/linux_android_rel_ng/builds/196952

shows no trouble with that CL in scope. Current builds are running with that reverted, though.

Comment 12 by guidou@chromium.org, Dec 13 2016

Status: WontFix (was: Assigned)
I don't see any flakes in the most recent builds.
The only flakes I see are builds with hundreds of failed tests, such as
https://build.chromium.org/p/tryserver.chromium.android/builders/linux_android_rel_ng/builds/197355
https://build.chromium.org/p/tryserver.chromium.android/builders/linux_android_rel_ng/builds/196988


The flakiness dashboard doesn't look bad to me. 
http://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=content_browsertests&tests=WebRtcDataChannelTest.DataChannelGC

Please reopen if this becomes  an issue again.
