The files transferred are created in the location, mapset and machine 
specific .tmp directory, so unless something bad happens, GRASS ought to 
delete them at end of session, if I understand correctly. The scripts 
could be altered to unlink directly, but sometimes leaving them around 
during the session may be helpful for debugging.

Hope this helps,
