Mongos topology leaks memory on every re-connect via the serverDescriptionChanged event listener

      The issue occurs only when using the "mongos" topology. Removing the offending event listener on connection close seems to solve the issue:

      db.s.topology.s.mongos.on('joined', (_, server) => {
	server.once('close', () => {
		server.removeAllListeners('serverDescriptionChanged');
	});
});
