Clear cache when blog is switched?

Hi!

Author of Broadcast here. It copies posts / pages / etc between blogs in a network install.

I have a user that uses Broadcast together with S&F Pro and is having problems with the broadcasted post not appearing on the child / target blog unless the post is saved on the child blog.

I’m thinking that it is the post caching that is causing the trouble.

I would like to clear the cache during broadcasting, while the network is switched to the child blog.

I was looking at the refresh_cache() function, but it ends with an exit(), making it useless for me.

Is there a way to clear the cache programmatically, taking into account that the blog is switched from the blog WordPress was originally loaded on?
