Comment 2 for bug 706248

I think I've found which Unity-2d processes are hanging at session logout
* unity-2d-places
* unity-applications-daemon
* unity-files-daemon

launcher, panel and spread always close quickly.. places and these 2 daemons sometimes hangs for 5/10 seconds.

I took a screenshot when this happen, terminal is still alive during session shut down so I was able to "ps -ax | grep unity"
