I tried an experiment.  I clicked on the "close window" button of the 
running gnome-terminal and verified that all subshells died.  However, 
when I click on the "logout" button on my Panel, the gnome-terminal dies 
but the subshells continue on (and on, and on, ...)

What does gnome-terminal do differently in these two cases?  I tried to 
look through the source but I cannot see any place where gnome-terminal 
actually signals the subprocesses running in its tabbed windows.

This situation causes a lot of difficulty.  For instance, if I run 
screen in a window, since exiting gnome-terminal does not signal the 
parent ksh, screen never receives the hang-up so the screen never detaches.
