Self correction here. Of course that's assuming 1 sort on average per
query. My experience is that you generally use less than that. Except
when you don't. :) If your typical query has 6 or 12 sorts in it,
your memory can run out fast. But judging by your current free RAM,
I'm guessing it doesn't do that. Only thorough testing can tell you
the sweet spot tho.
