  * flux_logout freezes fluxbox when i.e. gkrellm is still running.
    in that case the following message is dumped to the console:
    
    'Xlib: unexpected async reply (sequence .x......)!'

    if you experience a problem with an app other than gkrellm, 
    please contact the author.
    
  * add a manpage?

  * code-cleanup
  
if you have any suggestions or ideas how flux_logout could be further
improved, please contact the author!
