I'd like to tail-drop packets from specific queues if the machine load
is very high, instead of letting them build up ...

Hmm i don't think so. Queueing is done just before hardware transmission, so (almost) all processing has already being done at this point. Also since you only queue packets you're sending you could only protect other machines, but then you don't know their load ...
