Oh, we should have followed up on this. We worked with Steve for a bit, and
tracked it down to the stale-while-revalidate plugin. Since this plugin is dead
now, I don’t think it’s worthwhile to try to fix it (but, we’ll take patches
for 7.1.x if anyone wants to work on it).
We need a better alternative for stale-while-revalidate, since the plugin has
always been pretty darn crippled :).
