Doesn't pass in time with race detector enabled.

We may fire notifications asynchronously. Well, we have to, really. We'd like:

1. Begin Open
2. Open Notifications
3. End Open
4. Begin Close
5. Close Notifications
6. End Close

However, this breaks if we allow open notifications to close connections (which,
IMO, we want).
