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. +
