/tmp doesn't have to be used only for auxiliary files created temporarily by
various applications. I remember doing Emacs compiles on a lightly loaded
SPARC-20 (bi-processor) with 128MB:
> mkdir /tmp/emacs; cd /tmp/emacs; ~/src/emacs-19.34.91/configure
doing it this way was substantially faster and yet, it doesn't seem to be heavy
metadata-wise.
