It might be unstable, but I've been running with it for over 2 months without issues. If you still don't want it in, just leave out the domain part and just add the timeout :).
Stability is also about if Node is going to support this feature the way it does now in new versions of Node (eg. unstable means they can't promise backwards compatibility).
Added a 5 second timeout and a domain wrapper around the http request to make sure we have no unexpected crashes.
