If you are not using a session manager, you don't get session 
management.  Sawfish is a window manager, not a session manager.  The X 
reference implementation of session management is xsm, but desktop 
environments provide their own session managers.  Session management 
uses a separate ICE-based protocol rather than the X protocol.

This approach appears unworkable.  Delete-window-safely merely sends a 
WM_DELETE_WINDOW client message to the window owner as specified in the 
ICCCM.  The owner may react by prompting the user, e.g., whether to save 
changes, yes, no or cancel.  If the user chooses cancel, the window is 
not closed.  The wm is not notified of this user interaction in any way.  
So the wm would need to wait for the window to disappear to be sure that 
no data is lost but it cannot wait for that because it might never 
happen.
