Awesome tool. This is something I was struggling with node.. I had so many processes starting with "node /...." that it was a real pain to track what was doing what, which one to restart, which ones are zombies, etc etc. I won't lie, this is actually one of the reason I was still hacking the backend with python/django.. the virtualenv, gunicorn and supervisor just made it awesome. I'll definitely give PM2 a try though.

To other node.js users: How do you cope with this problem? I know friends who by-pass all this by using heroku (or similar platform), is that what you do? What about managing multiple node projects on a single linode instance?
