Suspecting this roll to blow up the webkit layout tests in debug mode:
https://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2064%20%...

Waiting for the chromium side bot:

[Michael Achenbach, 2017-02-07 19:16:47]

Heads up Chromium sheriffs. The v8 upstream webkit debug bot is in a bad state
since some commits in this roll:
https://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2064%20%...

So far nothing else broke and the chromium bot is still running:
https://build.chromium.org/p/chromium.webkit/builders/WebKit%20Linux%20Trusty...

If it breaks in the same way (i.e. lots of timeouts), feel free to revert this
roll and also the subsequent one with version 5.8.142 that already landed in the
mean time.

Rolling is already closed.

Are you already bisecting/investigating?

Nope, also not planning to...

FYI: Speculative upstream reverts are rolling:

FYI: Chances seem to be high that V8 just has a broken upstream bot :( Chromium
seems resilient to our problems...
