TEST=manual

Anyone who can take a look at this patch, specifically for the ChromeOS 552d
branch, and confirm that it shouldn't do anything terrible, we would like to get
it in for testing ASAP. 

Note: This code will be more properly reviewed for trunk at
http://codereview.chromium.org/5492001/

Thanks!

As a quick fix for the branch it seems ok, but I think we might want a different
solution for the long term. 

Can someone add me to the CC list on the bug so I can view it? I'd like to
better understand the motivation for the changes.

I added you, Aaron and Sam to the bug.

I'm really concerned that we've rushed a bunch of changes in this part of
the code.

Closing this issue and relying on Dmitry, et. al. to ensure that this is fixed
properly in trunk.

I committed my patch to trunk few days ago.
