What is clean_temp?

[WenLing]

We have a problem that has completely mystified us.  When one of the 
users of our system runs a long shell script, the memory gets almost 
completely used up by a GRASS program called clean_temp, found under
[grass base]/etc.  When other users run GRASS, this program is not called
and everything runs fine.  

What does this program do?  Why is it called?  Why is it eating up all the
memory (at least 7 Mbytes of RAM)?  This is the sort of thing I don't know
how to find out in GRASS.

Thanks for any help or suggestions.
