QRYDTA  this can cause a  ResultSet to close prematurely if a query is executed against the
second database before  all results are fetched from the server.

Also I failed to mention that  actual problem in the user case  I am  
looking at is a  Disconnect exception.  I don't see how this could 
relate really, but thought I would mention it since this issue arose out 
of  looking at their trace files and we don't have a reproduction yet 
for their Disconnect Exception.

If anyone can think of a way this could cause a DisconnectException, 
speak up.
