SubjectRe: 2.6.39-rc4+: oom-killer busy killing tasks

I've run the -12 test with vfs_cache_pressure=200 and now the -13 test
with vfs_cache_pressure=10000. The OOM killer still kicks in, but the
machine seems to be more usable afterwards and does not get totally stuck:
http://nerdbynature.de/bits/2.6.39-rc4/oom/
- messages-12.txt.gz & slabinfo-12.txt.bz2
* oom-debug.sh invoked oom-killer at 01:27:11
* sysrq-w works until 01:27:08, but got killed by oom

- messages-13.txt.gz & slabinfo-13.txt.bz2
* find invoked oom-killer at 08:44:07
* sysrq-w works until 08:45:48 (listing jbd2/hda6-8), then
my debug script got killed

Thanks,
Christian.
