Is this a test race condition where addTab() thinks the DOMContentLoaded has been fired, but the tabs_count UI element has not been updated yet?

Also, if I enable Android's "Don't keep activities" developer option, I see that testNewTab's `activity` variable is onDestroyed() after each addTab() call. Could this be a contributing problem?
Notice that BrowserProvider.updateHistory is doing sql work in a background thread in most of the recent traces. Several also have DB access on the main thread -- bug 856621 probably -- but not all. For example, Comment 26. 

The test failure is a result of the time-out waiting for the UI thread which is "only" 3000 ms. I wonder if increasing the timeout in RobocopUtils.runOnUiThreadSync would resolve some of these failures (maybe our responsiveness expectation is not reasonable when considered over thousands of test runs).
As expressed in Comment 26, I wonder if some of these intermittent failures can be avoided with a longer timeout, and if our current responsiveness expectations are unreasonable, given aging test devices and the inevitability of timing variation over thousands of test runs.

increase wait for RobocopUtils.runOnUIThreadSync

Review of attachment 774740 [details] [diff] [review]:
-----------------------------------------------------------------

LGTM. Alternately, you might also consider swapping the order in which textNewTab.java.in loads robocop_blank_01.html and robocop_blank_02.html. I wouldn't expect that to fix the test, but it might give us data about whether the test failure is related to the file robocop_blank_02.html or just whichever file is loaded second.

Curiously, robocop_blank_02.html is "less blank" than robocop_blank_01.html because it includes an embedded data:image favicon. Maybe the data:image decode time is causing problems or delays.

Great observations Chris - thanks. I will just try this for now, but follow-up on your idea if / when this bug is re-opened.
