I won't have a chance to try your suggestions until next week.  Though
I'm not convinced that handle_shutdown_signal is even getting called,
since I'm not seeing the diagnostic print statement, neither on the
console nor where stdout/stderr is being redirected.  I did try using
the kill command from the console to issue SIGTERM to the process
(e.g. kill -s SIGTERM <pid>) and I still got the infinite series of
"warning: unhandled exception" messages.
