 In all three version (6.4, 6devel and 7), I get the following error
 running r.terraflow in the North Carolina demo data set:

 I have over 60GB of disk space in /home (and I get the same error running
 it with the default /var/tmp). This is using Debian Lenny. The same error
 has been reported by a student running Ubuntu Intrepid.
