Script: https://gist.github.com/evNN/ea170966c078af4c02dc

I'm connecting to a replica set with a primary, secondary, and arbiter (3 separate boxes). I've replicated the setup on local on the same host name for testing. It seems that this script will never exit because the database connection is never closed when calling `db.close()`. The same behavior is present on our Ubuntu 14.04 boxes as well.

Any ideas? I've tried force-closing via `db.close(true, cb);` to avail.
