Rooting around in the directories, I was unable to find out
where these temporary files might be located.
There is a .tmp directory in every mapset directory. Beneath that will
be a directory called by your machine name. I've learned to ln -s the
latter to a big empty /tmp ever since my /home partition where I keep
grass data filled up solid doing similar things a few betas back.
Every mapset has its own .tmp. I don't know if there are collision
issues with this in the big scheme of things, but as I'm using only one
grass session and thus mapset at a time there seems to be no problem
with aiming all .tmp/machinename references at the same bucket.
