Heh, I wrote that :)

No, that's definitely not what you're asking for. It's the most
misleading title imaginable!

The title is generic across all 0MQ language examples -- but Erlang
doesn't support "handling ctrl-c cleanly". The example shows what the
equivalent shutdown handler might look like.

Sorry about that.

I'd still suggest a wrapper script in something like Python, which
handles signals well.

Btw, given Erlang's server side heritage, I'm surprised it *does not*
handle signals. Most background OS processes do.
