Description

AtomicBox<T> is a Box type designed to be used across threads, however, it implements the Send and Sync traits for all types T.

This allows non-Send types such as Rc and non-Sync types such as Cell to be used across thread boundaries which can trigger undefined behavior and memory corruption.
