  - HookQueue: Rename constructor 'queue' argument to avoid confusion
    
    The `queue` argument gets assigned to the `workQueue` member, but
    there is also a `queue` member.
    
    Rename the argument to `workQueue` to match the member that it gets
    assigned to, and prevent possible confusion with the other.
