4242 - get rid of refcounts entirely

We're going to lean back into the experiment of commit 4179 back in Jan.
If we delete memory it's up to us to ensure no pointers into it survive.

Since deep-copy depends on our refcounting infrastructure, it's gone as
well. So we're going to have to start watching out for pointers shared
over channels.
