r134144 seems to break Win7 chromium browser tests.

The following tests started to fail since http://build.chromium.org/p/chromium.webkit/builders/Win7%20%28dbg%29/builds/8232.

- PrerenderClickToPlay
- PrerenderNaClPluginDisabled
- PrerenderNaClPluginEnabled

r134144 seems to be related. Let me rollout that and watch the result.

All reviewed patches have been landed.  Closing bug.

Really?  I thought that patch just added some tests...

I am pretty sure the problem is with the builder.

For the record this was indeed my fault (one tiny line added to the product itself to support the tests, and I missed adding braces).  See bug 100550 for details and improvements to make it harder to hit this specific issue in the future.  Sorry for the trouble.
