GHSA-v42f-j8fx-99f3: Queue<T> should have a Send bound on its Send/Sync traits

August 25, 2021

Affected versions of this crate unconditionally implements Send/Sync for Queue<T>.

This allows (1) creating data races to a T: !Sync and (2) sending T: !Send to other threads, resulting in memory corruption or other undefined behavior.
