Could the problem be that without CONFIG_NUMA, zone_reclaim_mode stays at zero and anyway zone_reclaim() does nothing in include/linux/swap.h ? Though... there is no CONFIG_NUMA nor /proc/sys/vm/zone_reclaim_mode in the Ubuntu non-PAE "plain" HIGHMEM4G kernel, and still it handles the "sleep test" just fine. Where does reclaiming happen (or meant to happen)?
