What value does this actually have? Presumably so we get a backtrace in order to identify the errant caller. I added a bit to the changelog: : The pool is being destroyed so all pages which are in the pool should be : free. If some page is still in use by somebody, we should not just output : error logs, also should also add a WARN message so the stack backtrace may : be used to identify the caller.
