Alternately, setting the task priority to RT (it _is_ an AV

This is a really bad idea, bordering on useless scheduler abuse, IMHO.
IO is not prioritized on darwin (altho it may be deprioritized...),
its handled first come first serve. Your realtime thread will page
just as fast as non-realtime threads, especially since every page
fault you take will allow several ms of time for other lower priorty
threads to get their fault requests into the queue. RT goes out the
window across IO, except for pure scheduler latency... but I'd bet
just about anything that isn't the problem here.
