      Description

      A small window exists when a sort has finishes the gathering, sorting and spilling phase and is about to deliver rows, whereby a small utility allocation can cause OOM ("Memory limit exceeded").

      This is very unlikely in a standard configuration, but in a multi-channel configuration with lots of simultaneous threads potentially all exceeding their limits at nearly the same time, it becomes a lot more likely.
