Potential issue in process exiting

[wperrigo]

When the node process is aborted (ctrl+c) it hangs permanently at Closing all connections and exiting...

To fix I added process.exit() to the close method. Is this a known issue?

Yes, I've noticed it myself a few days ago.
Indeed process.exit() needs to added, but first the code needs some refactoring as the method close() is async and just adding process.exit() to the end of it will break all async processes going on.
I'll do this refactoring and release the new version next week.

I also encountered it, raised a PR with a fix in #58
