This is different because we are not trying to guarantee that a RowLocation is valid from
any container, only from the container it is being used from.
If a container is dropped, a cursor which has an open scan against it should fail. 
For holdable cursors, this should fail when trying to reopen the dropped container after a
commit. I think this logic already is in place in Derby.
