Action after cache flush

[Unyson]

Please add an action ​here so we can also flush ​our custom cache

Adding an action here wouldn't be advised.

The object cache is designed to be replaced entirely by drop-ins (wp-content/object-cache.php), so you wouldn't be able to rely upon the action actually being fired when someone was using an Object Cache.

Do you have a reference for how this Cache API you've linked to actually works?

Usage example is in ​class comment.

Main features:

• Throws if cache key not found
• Easy access nested keys by "multikey" format: a/b/c is equivalent to $cache['a']['b']['c']
• Auto flush is executed "​regularly" to prevent php memory full. Cache array keys are ​deleted one by one until php memory has ​10Mb free

It sounds like this should be using some kind of Object Cache dropin in conjunction with your custom handlers, I don't think I see any valid reasoning for adding hooks here.
