Browser process gets stuck endlessly using >100% CPU (spinning on one core)

Project Member Reported by msnel...@google.com, Jun 16 2016

Issue description

Chrome Version: 52.0.2743.32 (Official Build) beta (64-bit)
Chrome OS Version: 8350.21.1 (Official Build) beta-channel samus
Chrome OS Platform: Pixel2

Please specify Cr-* of the system to which this bug/feature applies (add
the label below).

Steps To Reproduce:
(1) Shutdown
(2) Restart previous browser state (loading multiple tabs)
(3) Browser process ends up with at least one thread endlessly spinning.

How frequently does this problem reproduce? (Always, sometimes, hard to
reproduce?)

With M52, always.  4 reboots and counting, all end up with the parent browser process spinning and consuming a full core endlessly. 

What is the impact to the user, and is there a workaround? If so, what is
it?

Entire system is sluggish, battery life is reduced. 

Please provide any additional information below. Attach a screen shot or
log if possible.

(Happy to generate and attach a log, but unable to find instructions on how to generate one)

What is the URL for the problem web site ?
Do you see this in incognito mode ?

Comment 5 by msnel...@google.com, Jul 18 2016

 This issue is not driven by a specific website, the process that is spinning is the core 'browser', not any of the pages.  Killing/ending other page tasks does nothing to immediately reduce/remove CPU load in the Browser task. 

Once triggered, the issue persists in incognito mode.
