Slow Shutdown when Network Mgr closes before CIFS unmounted
Are there any plans to replace Network Manager with Wicd?* I have always found it much easier to set up networking with Wicd.

Hello,
I am working on a fairly well-known ongoing problem where you have a slow logoff if connected wirelessly to a Samba share.
You get the message 'CIFS VFS: No response ...' and it takes about 2 minutes for the laptop to shutdown.
Apparently it happens because Network Manager closes down before the CIFS mounts are unmounted.
It will probably be some time before this gets fixed at the root cause but there is a good work-around for Gnome.
It entails running a process in the Gnome session that waits for the 'save-yourself' event (see below).
Is there a similar closing-down event that can be hooked into with an XFCE session ?
Would anyone be able to supply the few lines of code required in main() below ?
I could then test and, if successful, post the solution back into the Ubuntu forums article below.*

#This program runs a custom command/script just before gnome shuts

#If the custom script/command fails with a non-zero return code, a

#Usage: 1 - change the command in the 'subprocess.call' in

#********** you want to run at logout.
#****** 2 - Run this program at every gnome login (add via menu System
