Thanks for the revert, LGTM.

Dcheng: As far as I see
http://build.chromium.org/p/tryserver.chromium.win/builders/win_chromium_x64_...,
it looks like a ton of tests are crashing, but I can find an informative log
only in the ScriptContextSet.Lifecycle's log:
http://build.chromium.org/p/tryserver.chromium.win/builders/win_chromium_x64_...

Do you know if other tests are failing with the same ASSERT?

[dcheng, 2015-02-05 08:29:24]

I'm not sure. Unfortunately, I wasn't able to reproduce the failures at all
today, which is why we ended up using the trybots to help us bisect the issue.
