Subject: [PATCH 333/333] Ticket #48192 - Individual abandoned simple paged
 results request has no chance to be cleaned up

Description: Checking the cookie value passed by the client was not
sufficient.  The negative value check was missing, which lead to
the simple paged results array out of bounds.  Plus, a minor memory
leak was fixed.  Thanks to Thierry Bordaz for his reviews!
