[dev] [dwm] terminating the status loop

[Thomas Dahms]

Hi list,

using something like
  while true; do
      xsetroot -name ...
      sleep 1
  done &
  exec dwm

in .xsession (I have to use KDM at work) as advertised in dwm's README  
leaves the background loop running even after logout, which has some ugly  
side effects: While not logged in, xsetroot floods the logs because it is  
unable to find the display. And logging back in, I have two loops running.

The following fixes the problem:

  while true; do
      xsetroot -name ...
      sleep 1
  done & statuspid=$!
  dwm &
  wait $!
  kill $statuspid

This looks quite ugly and I am curious if there is a more elegant way to  
terminate the status loop on logout.
