Beware that Python's atexit isn't reliable (unless SCons already fixes 
it).  Most signal-based terminations bypass the normal exit stuff 
(including atexit handlers), so you need to add your own signal handler 
that calls sys.exit().  And since the "Terminated" message is part of the 
default signal handler, yours needs to print a message if you want one.
