> Seems, a race possible on MapQueryResult*s*.close() as this code can be called twice.
> Let's rewrite it make sure every map result is closed via MapQueryResult*s*.closeResult(int) method only.
> Then allow cleanup once all map results are closed.
> Then MapQueryResult*s*.allClosed() can be optimized as we always know number of map results and all map results are closed via MapQueryResult*s* instance.
> Seems, MepQueryExecutor.onQueryRequest0() has dead code. See "res.openResult(rs)" call when 'null' passed as argument.
>  
> Start point is MapQueryResult.openResult(res).
