action for full cache purge?

I had a look around in the code, but I can't seem to find an action I can hook into that fires when the cache was fully purged.

My use case: i want to purge Autoptimize's cache when WPSC's is cleared, but only when WPSC's is entirely purged (else we risk having pages in WPSC that refer to non-existing AO items).

So:

* is such an action available (I might have missed it)
* if not; could it be added (I guess in wp-cache-phase2.php in the wp_cache_clear_cache function, I could whip something up and do a PR)?

Start in wp-cache-phase2.php at wp_cache_clear_cache, as identified in the issue, and inspect how the full purge currently completes and which actions are available. The work is done when a hook fires only after the entire WPSC cache has been purged, allowing Autoptimize to clear its cache safely; no test file is mentioned.
