Well, that's why I was soliciting developer input as to exactly what
goes on with sorts.  From what I seem to be hearing, all sorts result in
temp files being created and/or used.  If that's the case then yes, I
can understand the fixation.  Of course that opens the door for it being
a horrible implementation.  If that's not the case, then parallel sorts
still seem like a rather obvious route to look into.
