Summary: If GC kicks in between * A Get() reads index entry from base db. * The Get() read from a blob file The GC can delete the corresponding blob file, making the key not found. Fortunately we have existing logic to avoid deleting a blob file if it is referenced by a snapshot. So the fix is to explicitly create a snapshot before reading index entry from base db.
