 8. `connect(#timeoutAfter:Int, withTimeoutHandler handler:(() -> Void)?)` - Connect to the server. If it isn't connected after timeoutAfter seconds, the handler is called.
 9. `close(#fast:Bool)` - Closes the socket. Once a socket is closed it should not be reopened. Pass true to fast if you're closing from a background task.
 10. `reconnect()` - Causes the client to reconnect to the server.
+11. `joinNamespace()` - Causes the client to join nsp. Shouldn't need to be called unless you change nsp manually.
+12. `leaveNamespace()` - Causes the client to leave the nsp and go back to /
