> right now we are using too much of the old get code, we need to review that and constrain how this works but without breaking ICV.
> Also we should be resetting the timestamp on every ICV call, and removing the older version.  Instead of 'updating' an ICV "in place" we should be adding a new one, removing the old one from memstore (if it is there).  This will play well with the atomic approach added in HBASE-2248 since we are only touching 1 KeyValue at a time.
