Sorry, to expand on my all too brief comment, even *without*
replication, they are hosed.
Once you issue commit, you have know knowledge if the commit is
durable, (or even posibly seen by somoene else even) until you get the
acknowledgement of the commit.
That's already a posibility with a single machine databse. Adding
replication in it, just increases the perioud that window exists for
(and the possiblity of things making something "Bad" hit that window).
