>          Issue Type: Bug

>            Reporter: Paul Rogers
>            Priority: Minor

> The external sort operator performs in-memory or on-disk sorting. Several functions within external sort can take an extended time. During this time, the operator does not check if a query cancellation has occurred. These long events are:
> * Spilling a group of batches to disk
> * In-memory sort
> Note that "re-spilling" of spill files is covered by the first item above: re-spill uses the same code to write the new file as is used for the original "first generation" spill files.
> Also, the final merge is handled because the downstream operator will check for cancellation prior to fetching each batch from the sort operator.
