> One issue that we get in the users list is result set being used after the associated query execution has been closed. This may become more significant when/if {{QueryExecution}} becomes {{AutoCloseable}}.
> To support a ResultSet implementation that checks whether the {{QueryExecution}} is still current, add e.g. {{QueryExecution.isClosed}} to test for the state of the {{QueryExecution}}.
