While I investigate the session history, we should check to see if the failures
were due to duplicate routing ids, an issue that was fixed last Friday with
https://codereview.chromium.org/642813007 .

[Charlie Reis, 2014-10-20 18:31:26]

Yeah, there's a chance duplicate routing IDs could have caused these failures. 
LGTM to find out.
