>
> The C++ client swallows the query_completed status message because it has
> already signaled the end of data thru the ls_last_chunk.
> However, it may be too early for the application (or odbc driver) to free
> resources.
> The API should provide a clean method for detecting the completion of the
> query. This may include calling the listener callback one more time with no
> records, but with the query state set to completed.
