32.3%-1442.8% regression in time-to-play for multiple media.tough_video_cases at 456690:456834

Project Member Reported by chcunningham@google.com, Mar 16 2017 
Dozens of tests across windows bots showing similar regression. 

Revision range matches similar regression in process_delta metric ( Issue 702268 ) for windows bots. 

Also seeing regression in working set memory metrics in this revision range (and on these bots).
