This entire discussion, and your involvement in it, originated from these
two patches being merged into -mm:

oom-prevent-unnecessary-oom-kills-or-kernel-panics.patch
oom-skip-zombies-when-iterating-tasklist.patch

So naturally I'm going to challenge your testcases with the latest -mm.
If you wanted to suggest pushing these to 2.6.38 earlier, I don't think
anyone would have disputed that -- I certainly wouldn't have since the
first fixes a quite obvious panic that we've faced on a lot of our
machines. It's not that big of a deal, though, since Andrew has targeted
them for -stable and they're on schedule to be pushed to 2.6.38.x
