Review Comment:
Oh, we can't remove this method. because we have removed the cursor from the
waitingCursor when consumer unsubscribe. and there are still race conditions
with `consumer.close` and `checkForNewEntries`.which will lead to OOM
You can use testAddWaitingCursorsForNonDurable to reproduce
