Why does logging out of gnome leave the ksh93 processes still running 
with ppid init?  During normal operation, the ksh93 processes have ppid 
of gnome-terminal, with pgid of themselves.

When I hit the big X on the upper right of my window (the only way I 
know of to simulate termination of gnome-terminal at logout), all of the 
shells die.  When I press the logout button on the Panel, gnome-terminal 
dies but the shells linger on.  Please explain this behavior in a way 
that makes sense.
