Thanks Jannis. I think I'm getting the point now. BTW, I just realized 
that there's another function that doesn't really fit power manager - 
Logout.

One alternative would be to implement "save session" in the session 
manager and move the (actual) shutdown and restart code to the power 
manager (this would require the user code to call both the session and 
power manager to e.g. save the session and shutdown the machine). I 
believe this would be a "cleaner" design, but then, the Nick's proposal 
has a big practical advantage of not requiring power manager with all 
its dependencies for shutdown and restart.
