> Don't bother validating workspace nodes at commit time if none of the nodes have been modified in the tx.  Throws unnecessary exceptions.
> E.g.:
>   Transaction A reads object 1
>     Transaction B modifies object 1
>     Transaction B commits
>     Transaction A commits
>    Will throw an exception, which is probably not desired.
