I dunno about dbmirror, but rserv and its bigger cousin both actually
apply the current-as-of-snapshot version of the row (which means that
if you have multiple changes to the same row, you needn't go through
all the iterations when applying the snapshot). I presume the same
is true of dbmirror, since it relies on the primary key.

Yes, if it works as advertised, it'd be a _mighty sweet_ piece of
technology.
