An issue was discovered in the v9 crate through 2020-12-18 for Rust. There is an unconditional implementation of Sync for SyncRef<T>.
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.
