> The inflight calculation is reworked to be thread-safe for 2
> threads - note this is not general multi-thread support, i.e
> all enqueues to a qp must still be done in one thread and
> all dequeues must be done in one thread, but enqueues and
> dequeues may be in separate threads.
> Documentation updated.
