+This module is an experiment about a more graceful shutdown process.
+
+Why
+===
+
+When shutting down, a number of sessions, connections and other things
+are teared down. Due to all these things happening very quickly,
+sometimes eg client unavailable notifications don't make it to all
+remote contacts because the server-to-server connections are teared down
+just after.
+
+How
+===
+
+This module works by breaking the shutdown process into separate steps
+with a brief pause between them.
+
+It goes something like this
+
+1. Stop accepting new client connections.
+2. Close all client connections.
+3. Fire event for everything else.
+4. Tell `net.server` to quit the main loop.
+5. ???
+6. Still here? Kill itself.
