Umm, you lock the data, then you destroy it.  Destruction is just like
any other modification, except that there's nothing left to unlock
when you're done.  Hmm, how do we politely tell the guy waiting for
the lock we destroyed to have better luck next time...  Maybe don't
free the memory until we lock the arena page.
