I think it could be implemented. Depends whether items->availableApprox() being non zero guarantees an item is there, which I believe is the case.

Yeah, it would work because the consumer thread necessarily sees its own decrements on that semaphore, so if it sees the semaphore at non-zero, there must still actually be an element.
