Well as I understand it everything else will be preserved: it is just 
LD_LIBRARY_PATH that is unset; is that right?
What about just setting another variable in Init.sh? After the correct 
LD_LIBRARY_PATH for the GRASS session has been determined and set,
copy it also to GRASS_LD_LIBRARY_PATH. That wouldn't be unset by xterm and
then it could be restored to LD_LIBRARY_PATH in the script. Although I
suppose if the user changed their LD_LIBRARY_PATH after starting the GRASS 
session something might be missing, but that would probably be quite unlikely.
