Yes. I ran my stress load with Nishimura-san's cpuset migration test on
x86_64 and ia64 platforms overnight. I didn't have all of the memcgroup
patches applied--just the unevictable lru related patches. Tests ran
for ~19 hours--including 70k-80k passes through the cpuset migration
test--until I shut them down w/o error.

OK, I did see two oom kills on the ia64. My stress load was already
pretty close to edge, but they look suspect because I still had a couple
of MB free on each node according to the console logs. The system did
seem to choose a reasonable task to kill, tho'--a memtoy test that locks
down 10s of GB of memory.

I'll restart the tests with this series.
