I think it use it to put some of the code there (overlays, etc).

Take a look in the manual and find that section (apendix) who describe WP
switches. There you can find a switch that tell wp to store temporary files
somwhere else, a good examples is to store those i a ramdisk (if you have a
large ramdisk)!
I cant remember this switch right know but there is one to do this!
