Speaking of which, it might be interesting to actually show these

good thing.


What 3 columns? In-memory sorts, on-disk sorts, and on-disk size?
(Sum of how much spilled to disk).

I was thinking in-mem sorts, on-disk sorts, limited-by-LIMIT sorts (that
would be the new feature..)

It would also be useful to know how much got spilled to disk. If it's a large amount per sort, then there's probably not much you could do, but if it's just a tad over available memory per-sort...
