Hi Ben.  I'm glad you mentioned tmpfs, since I was going to but managed to
forget :)  Using tmpfs is faster (temp files are kepin ram or swap), and
saves disk space (since now /tmp & swap are on the same area of disk).

One caveat for using tmpfs:  /tmp & swap are now on the same area of disk.
If /tmp fills and takes swap with it you might have an unhappy system.
Solaris in particular seems to really dislike this.  The solution is to
limit the size of /tmp so it isn't as large as swap.  Under Linux set the
size= mount option on /tmp.  Here is my /tmp line from /etc/fstab:

swap            /tmp    tmpfs           defaults,size=1024m     0       0

Cheers,
	-Rob
