Is this something I need to worry about and perhaps
try to change? Or can I work my way around this and
just ignore it?

It does, but the debugger part is still something I'm
working on...

I'm not sure about this, I didn't write the program.
I'm trying to get in touch with the person who has
written it, but this can take quite a while. I think
I'm going to investigate this on my own...
Anyway, if I leave 'alarm' out of my code, the program
runs, but crashes on CTRL-C, but if 'alarm' is still
in there, the program crashes while running.
