# richard.coe@med.ge.com   GSAge16522   Xorg crash when closing down appgroup process
# 20 Nov 2009
# This patch fixes a crash in the Xorg server when the appgroup leader has exited and 
# windows from the appgroup session are left open and eventually close.
# The issue is caused when windows in the appgroup are not correctly inserted into the
# appgroup list.  Since they are not in the list, the windows do not get closed at 
# appgroup shutdown.  
#
# I was able to reproduce this with two scripts:
# script: xltest
# while : ; do ./xlaunch -- ./xtest1 & sleep 1 ; kill $! ; done
# script: xtest1
# let i=0 ; while ((i < 20)) ; do xterm -geometry =20x20 & let i=$i + 1 ; done
#
