Going by the title of the second link +Craig Tumblison
provided, it looks like it is related to the App Launcher start page.
It is referenced here as well. https://code.google.com/p/chromium/issues/detail?id=308703
There are mentions of a "People API" in Craig's link as well. which leads me to believe there might be an integrated Google Contacts search coming to the app launcher soon. We have already seen indications of that elsewhere, and it would make sense that Android and Chrome would be calling from the same resource.
