WindowServerTest.EstablishConnectionViaFactory (mus_ws_unittests) is very flaky on several try bots

Project Member Reported by wangxianzhu@chromium.org, Dec 8 2016 
It's very flaky on at least linux_chromium_chromeos_ozone_rel_ng, linux_chromium_rel_ng, win_chromium_x64_rel_ng.

A sample:

Sometimes WindowServerTest.Visible also fails, but less frequently:
