描述
`ArcIntern::drop` has a race condition where it can release memory which is about to get another user. The new user will get a reference to freed memory. This was fixed by serializing access to an interned object while it is being deallocated. Versions prior to 0.3.12 used stronger locking which avoided the problem.
