Yeah, but is it _supposed_ to use that many temporary files? If it is,
then well, it sure does suck :) Especially since it's incapable of
sorting files larger than 704MB (according to the man page). Seems to me
that if it's going to be using the disk to store stuff, the largest file
it can sort should be constrained by available disk space. Anyways, I
never had to up my file descriptor limit with GNU sort...
