Waiting for cache cleaning before reading core_config_data in Magento 2 (Asyncronous)

Question

I have a scenario where I save a variable to the core_config_data table using an \Magento\Config\Model\ResourceModel\Config object:

$this->_resourceConfig->saveConfig(
                'mycompany/configuration/token',
                $token,
                'default',
                0
            );

then I clean the cache using \Magento\Framework\App\Cache\Manager and Magento\Framework\App\Cache\Type\Config objects:

$this->_cacheManager->clean([CacheTypeConfig::TYPE_IDENTIFIER]);

Immediately, I redirect to another page that recalls the the same config variable, but it's null.

How do we make sure the cache cleaning finished before trying to read config data?

I'm not sure if this was definitively solved, but after I upgraded to Magento 2.16, the issue was resolved. The coreConfig items are present between page loads now.
