It seems like this patch broke two TestWebKitAPI tests:
http://build.webkit.org/builders/Apple%20MountainLion%20Debug%20WK1%20%28Tests%29/builds/7944

http://build.webkit.org/builders/Apple%20MountainLion%20Debug%20WK1%20%28Tests%29/builds/7944/steps/run-api-tests/logs/stdio

Tests that failed:
  WebKit2.CloseThenTerminate
Tests that timed out:
  WebKit2.DOMWindowExtensionNoCache
