Crashes (segfault) with Socket.io v0.7 + Node engine >~v0.4.x .

I've noted this behavior not exclusively with this app but with other socket.io apps running in this combination of modules + engine. I can verify that we can run still run ok with socket.io 0.6.x. I also verified that Node v0.5 doesn't crash.

Regardless, we may want to add a package.json file to define the real dependencies. You don't need to publish this into NPM yet, but anyone using NPM can type 'npm install .' and it will go out and grab the dependencies (in case, for example, we have the wrong version of Socket.io installed globally).
