Description
The pre image truncate marker initialization code relies on abandonSnapshot() to provide an updated view of the pre-images collection, and update the highest seen recordId and wall time for each nsUUID.
However, (1) the code passes a CollectionAcquisition reference whose underlying collection pointer could be invalidated by calling abandonSnapshot() if there were a concurrent DDL operation.
At this time, the uses of abandonSnapshot() are called while holding the collection lock, which prevents DDL operations from coming in and invalidating the Collection snapshot.
