A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/2327583002/ by lushnikov@chromium.org.

The reason for reverting is: With the revert in place, the Linux MSAN is still
failing:

https://uberchromegw.corp.google.com/i/chromium.webkit/builders/WebKit%20Linu...

This proofs this patch to be innocent..
