We currently scan all the PHP files in the target WP content dir looking for wp_cache_flush() uses, however we are not currently using the results in a meaninful way so we can just probably return early if the current check found a match.
If there are plans to list the matched files, we can probably attempt to use some more performan alternatives (grep if available for example) which should be likely faster than a PHP based implementation.
