Ted, as previously discussed on this list, what you are saying is true
when the leader doesn't fail but it may not work in the general case
under some asynchrony conditions. Please see my email "sync semantics"
from Mar 1st or the thread "Ensure Leader hasn't changed" from
September 2012. In order to handle the general
case we should make the sync a quorum operation.
