The daemon could be made to clean up temporary files.  Currently the daemon 
works only in response to user-generated events so it would be something of 
an expansion of the concept, but not a big one.

Another option would be to modify a library routine (G_tempfile perhaps) so 
that it checks for and cleans unused temp files whenever it is invoked.  That 
would not keep .tmp completely clean but it would keep the temp files from 
building up.

A note about the daemon.  It it working very well.  I installed it over the 
most recent tarball I downloaded.  The updates to make it work were required 
by changes in GRASS since pre2, not by problems in the daemon code itself.  I 
still need to track down the cause of an odd error generated by clean_temp on 
exit.  I had a problem with location formats that I also need to track down, 
but that may have been caused by earlier troubles.  The last step will be to 
figure out how and where to install it in the GRASS hierarchy.
