[GRASS5] [bug #3298] (grass) GUI stop/continue button

fyi, the UNIX commands you speak of:

top

then hit "r" and type in PID of process eating 99% of the CPU. Set in
the range of 1-19, where 19 means the lowest priority.
Then "q" to quit.


or before starting the run reset the current shell's priority:

renice +19 -p $$



I add this to .grass.bashrc so GRASS always runs at semi-low priority:

GRASS_PROC="`pgrep Init.sh`"
if [ -n "$GRASS_PROC" ] ; then
   renice +15 -p $$
fi


(the pgrep test isn't really needed)
