I suspect we might want to launch X from ldm because of xauth security 
implications?  You want the xauth keys to change for each unique 
Xsession for security reasons, so users cannot hijack the previous 
user's X server.  You also want to ensure that all of the previous 
user's X clients are disconnected.  gdm forces this by restarting X each 
time you log out.

It currently does work even with xauth in the current implementation, so 
there is no dire need to change it.  I suspect the next major iteration 
of ldm might even be obsolescence if the functionality is implemented in 
a future version of gdm.  GNOME developers have talked in the past about 
wanting something like this.
