Currently, as part of initial_sync_drop_against_last_stable.js, we drop a collection and then create a new one with the same name. We also insert a document into the new collection and check that it exists once initial sync is complete. Currently, there is a race that the document is not covered by initial sync (the optime for the insert is > than the stopOptime for initial sync), and we fail the assertion that the inserted document exists after initial sync is complete.
