An issue was discovered in the abox crate before 0.4.1 for Rust. It implements Send and Sync for AtomicBox<T> with no requirement for T: Send and T: Sync.
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
