Comment:

 What the problem was:
 The signal handler would call save_notebook(), which would stop the
 twisted server.  There was a handler on the server shutdown,
 "reactor.addSystemEventTrigger('before', 'shutdown', save_notebook)", that
 would call save_notebook() again.

 Changes:
 Moved the code that stops the server into the signal handler, and removed
 the save_notebook call.
