-------------------------------------
Description:
A timed-out SQL query executed via thin client may leave the server-side cursor
registered after ClientCacheQueryCursor.writePage() fails while
fetching/writing the page. As a result, query-related objects remain reachable
from client resources, causing heap growth after repeated timeout cancellations.
