A good point! It seems that we have one or more leackages here.
Question is if we could add something to the temp file creation
routine G_tempfile() or so to find out the generating function
from the temp file. Maybe
8812.i.rectify

or so? Then I could watch the temp directory a while and
easily identify the candidates.

The problem is that clean_temp is only called when leaving GRASS.
If you stay in a session for one week or month (yes, that happens),
you just fill the temp space.
