Cannot create a custom adapter into Module.php

[e-belair]

if i want to create a custom adapter into Module.php i get an error: cannot create service with the same name.
It's because BjyProfiler contain a custom config who create a factory by default.
I suggest to clear the config file and just make its content optionnal.
There is an example who can generate the error:
i'm building a multi website application. Each website is a module and need to get it's own adapter, so i did that:

class Module
{
    public function onBootstrap(MvcEvent $e)
    {
        $eventManager = $e->getApplication()->getEventManager();
        $moduleRouteListener = new ModuleRouteListener();
        $moduleRouteListener->attach($eventManager);

        $this->bootstrapDb($e);
    }

    public function bootstrapDb(MvcEvent $e)
    {
        $e->getApplication()->getEventManager()->getSharedManager()
            ->attach('Zend\Mvc\Controller\AbstractActionController', 'dispatch', function ($e) {
// Comment this line to get the error
                $e->getApplication()->getServiceManager()->setAllowOverride(true);

                /** @var AbstractActionController $controller */
                $controller = $e->getTarget();
                $controllerClass = get_class($controller);
                $moduleNamespace = substr($controllerClass, 0, strpos($controllerClass, '\\'));

                $dbConfig = $e->getApplication()->getServiceManager()->get('config')['db'];

                // Global Application config
                $config = array_merge(
                    array_intersect_key(
                        $dbConfig,
                        array_flip(array('username', 'password', 'driver', 'dsn', 'options'))
                    ),
                    $dbConfig[strtolower($moduleNamespace)]
                );

                $controller->getServiceLocator()->setFactory(
                    'Zend\Db\Adapter\Adapter',
                    function ($sm) use ($config) {
                        $adapter = new \BjyProfiler\Db\Adapter\ProfilingAdapter($config);
                        $adapter->setProfiler(new \BjyProfiler\Db\Profiler\Profiler);
                        if (isset($config['options']) && is_array($config['options'])) {
                            $options = $config['options'];
                        } else {
                            $options = array();
                        }
                        $adapter->injectProfilingStatementPrototype($options);

                        return $adapter;
                    }
                );

            }, 100);
    }
}

So i have to set AllowOverride to true in serviceManager to get it working
