      SERVER-38852 describes a general problem of lingering operations which is probably much harder to solve. While investigating that we realized that $merge's writes are actually allowing an implicit creation of a collection. This may have been intentional to get the auto-create behavior for $merge, but it would be more robust to have the collection explicitly created, and that should be achievable.
