The results:
pre2+semaphore real 14m19.987s user 6m24.480s sys 1m12.970s
pre2+semaphore+throttle_IO real 10m13.953s user 6m19.980s sys 0m28.960s
pre2+semaphore+throttle_IO extended to refill_inactive() real 9m46.395s user 6m23.510s sys 0m29.420s
pre2+semaphore+throttle_IO + above + tiny little tweak to page_launder() real 8m56.808s user 6m23.420s sys 0m29.430s
Unfortunately, when I try to get past this point I burn trees :-)
