Broadening this to include other platforms, because it's happening on Linux, Mac, and Win.

On Mac and Win, the only story that's failing seems to be twitter.
On Linux, discourse, facebook, and twitter, all seem to be failing. I'm going to send out a CL disabling these now.

One thing worth noting: it seems that these same stories are already disabled in system health's infinite scroll stories. We should really come up with an architecture where we can be sure that disabling a failing story in one benchmark will also disable it in others where it's likely to be failing. Otherwise, problems like this seem likely to keep occurring.
