No, that's the problem and it has always been the problem: the queue never gets adjusted, because when the "adjust openings" request is sent up with, say, 120 openings, there are already 121 or more requests queued. This prevents the queue from being adjusted (XPT fails, doesn't propagate an error down but expects any interested drivers to try again in case of a failure)...
