Haven't followed this feature closely but my first thoughts when recently
reading about it were related to the initial copy and table synchronization
- so I'd have to agree with Petr here.  Full table sync is big and for any
table with activity on it the confidence level of knowing you have
everything is greatly reduced if the system isn't making a guarantee.
