 But memcached doesn't flush stuff after some time?

 I use WP File Cache plugin and by default it gets filemtime to know when
 cache was created, and if it's older than 1h cache is deleted and returns
 false. I changed default to 1 day and works fine.

 It's really scary having data eternally cached by default. Even more when
 wp_cache_add() only adds data to cache if it's not already cached, and
 wp_cache_replace() also only replace if data is already cached.

 A bug in any data editing code that doesn't delete cache may make old data
 be used forever.
