mod_muc_rtbl: Optimize case with zero hashes
On the assumption that during quiet times between torrents of spam,
the hash set would be empty. There would be no point in doing the
operations and hashes to check for a match in that case.

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 e.g. 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.
