2849270 - On sp_iqconnection , Created Temp table space is still kept , even after drop those table -- SAP IQ

A Replication ( ASE => IQ ) customer reported that a DSI session continuously holds Temp working space in IQ16.0, comparing to IQ15 which doesn't keep such working space at all.  Because of the concern, he worried about out of Temp db space.  He used 'sp_iqconnection' procedure to monitor status.

  Create table #SalesOrders( ID   numeric(4,0) ... ;
  Insert #SalesOrders select * from SalesOrders ;
  Commit ;
  Drop table #SalesOrders ;
  Commit;
  Select TempTableSpaceKB from sp_iqconnection() ;

In IQ15.4 , TempTableSpaceKB is 0 ( zero ).  Ie; all work space was released after dropped.
But in IQ16.0 Sp11.x, used temp work space would not be released until disconnected.
