Be careful to delete every process you'd created. There is at least a
wsh and csh hanging around.

The following shell script works on 3.1C and did work on 3.0D, 
as well as on a 4D/20G and 4D/70GT:

/etc/gl/grcond &
sleep 60
grcpid=`ps -fu $LOGNAME |grep '/etc/gl/grcond' |grep -v grep |awk '{print $2}'`
wshpid=`ps -fu $LOGNAME |grep 'wsh.*grconc' |grep -v grep |awk '{print $2}'`
cshpid=`ps -fu $LOGNAME |grep $wshpid |grep csh |grep -v grep |awk '{print $2}'`

your program

sleep 5
kill -9 $cshpid		# killing the csh will also get rid of the wsh
sleep 5
kill $grcpid		# no kill -9 here

finding the right process id's is not very elegant but it works.
