You mean that v-kernel will keep checking the timestamps and
automatically rebuild index when it is out of sync (besides using the
timestamps for transactions)? So each record will have a timestamp
and then the table will have its own, right? And table's timestamp
will reflect newest timestamp of its records and any
structural/property changes to table, right?
