For anyone in a rush, found this workaround until the bug is fixed. I personally have not tested this as I'm not using Node for production yet.

Lucky for me this was the first time I was going to use node on my Media Temple DVS and it was for testing purposes, but this is no joke.
I can't even imagine the trouble this is creating for anyone with multiple clients running on node.js
