Node script throws uv_signal_start EINVAL

I'm running Ubuntu 12.10 and getting started with Node.

I first installed node using the Ubuntu repositories. I ran into some trouble with something, so I re-installed using Chris Lea's repository. After that, node was running better, without that previous error.

Then I ran sudo npm install node-dev -g

But running node-dev script.js wasn't working.

Error:
node.js:762
          throw errnoException(process._errno, 'uv_signal_start');
                ^
Error: uv_signal_start EINVAL

The error isn't with node-dev, but rather in your script. Error: uv_signal_start EINVAL is thrown in newer versions of node when you're trying to work with SIGKILL or SIGSTOP, like so:

process.on('SIGKILL', function() { // etc, etc

You probably got away with this in earlier versions, but newer versions will now throw this error (see this GitHub issue for details).
