[Plugin: WP Super Cache] prune / garbage collection and wpmy

Hey

Im running a wpmu site version 3.3.2 (just upgraded but the problem whas also there before the upgrade). I have the problem that ALL my cache is eighter pruned og garbage collected aproximate every minutte. I have tried to eneble preload, this did not solve the problem. Also when someone is writing a new post, the intire cache is deleted for all blogs. Is this by design ? If all cache only lives for around 1 minutte, it does really help much.

I also have setup object-cache, but i have tried to clear all object cache in memcache after doing changes in the settings so im sure that its not just cached settings that is the problem.

Here is some debug output from the blog when someone did a new blo post.
