Possibly not, but normally a Python program will generate a traceback if 
you Ctrl-C out of it without explicitly catching KeyboardInterrupt. 
Should it be CherryPy's job to change that behaviour?

(Sorry I haven't checked the code: I wonder why it's catching that in 
the first place.  Little other non-application code does that... it 
should probably be up to the programmer to handle.)
