we tag queued buffers with the "bufferqueue cannot block" flag and use that bit to discard a buffer in the queue by new ones comming in. this allows us to remove the buffer queue drain in disconnect while maintaining the right behaviour if it gets connected again (since each buffer remembers how it was enqueued).
