This is also visible on GDG. Not sure why GDG hits it every time, and these things apparently only in the shard runs. Some kind of fb leak somewhere...

Yes this just indicates an fb leak in any of the previously run tests. module-reload is just the canary. So step 1: take note of all the previous tests run in the same shard, step 2: figure out which one it actually is. Yes this is one of the more painful ones.
