Intermittent browser/base/content/test/tabcrashed/browser_shown.js | This test exceeded the timeout threshold. It should be rewritten or split up. If that's not possible, use requestLongerTimeout(N), but only as a last resort. -

Not permafailing. I'd say it's about 50% failure rate. 

And I was wrong in comment 3. The chunk the test runs in keeps shifting, so it only looked like that backout merge caused the spike. I can try further tracking down where this started.

This was a long-running test before mconley's change:

Test durations for browser/base/content/test/tabcrashed/browser_shown.js on mozilla-central,mozilla-inbound,autoland between 2017-07-11 and 2017-07-18
linux32/debug-e10s:            103.66 s (82.71 s - 123.08 s over 193 runs)
linux32/opt-e10s:               24.69 s (20.94 s - 47.71 s over 231 runs)
linux64/debug-e10s:             97.67 s (79.46 s - 138.65 s over 285 runs)

With those durations, it seems odd that frequent failures were not reported earlier.

Regardless, we have the standard options: Find a way to optimize or simplify the test, split it up into 2 or more tests, or requestLongerTimeout(). 

Hoping mconley has time to fix this soon...
The simplest "solution"!

Also, I noticed and other tabcrashed tests already requestLongerTimeout().
