> Before DRILL-4215, the sort operator wasn't able to correctly compute it's memory usage, and so it jumped through a bunch of hoops to try to figure out when it should spill to disk.
> With the transfer accounting in place, this code can be greatly simplified to just use the current operator memory allocation.
