Easy way to kill a 5.x/6.x box as a basic user.

I have found that ImageMagick writes to (and often fills up) /var/tmp...my system becomes sluggish,
dies, reboots.

The solution I have used is to 1) create a /usr/tmp, 2) remove /var/tmp , 3) make a symbolic link
between /usr/tmp and /var/tmp.

Perhaps ImageMagick could be patched to use a /usr/tmp directory for scratch.

Alternately, if one knew that this would be an issue, /var could be made to be a larger filesystem.
