+ No table traversal will guarantee a consistent snapshot of the entire
+ table if the table is also updated by concurrent processes during the
+ traversal. The result of each concurrently updated object may be seen (or

+ of the table. The only way to guarantee a full consistent table snapshot
+ (if you really need that) is to disallow concurrent updates during the
+ entire traversal.
