Looks like this is driven by load_news.

I expect https://codereview.chromium.org/2284053002/ will "fix" this, although it's no surprise to me that v8 heap increases when there is no Flash (since pages are likely to load some sort of HTML5 fallback).

Register a fake Flash with chrome://plugins during browser start-up.
This enables websites to query for the presence of Flash using
navigator.plugins and navigator.mimeTypes even when we don't actually
have it.
