I don't quite follow this. What circumstances would lead to this situation?

BEGIN WORK;
DECLARE CURSOR ... ;
FETCH ...;  -- for some number of fetches, which does not reach the end of the cursor.

then just sit there idle, without having closed the cursor or fetching anything more.

So the fix in that case would be to ensure that they CLOSE the cursors when done with them?
