Umm, that wasn't the bulk of objection, was it?  We were discussion
the whole premise of userland oom handling and the conclusion, at
best, was that you couldn't show that it was actually necessary and
most other people disliked the idea.  Just changing a part of it and
resubmitting doesn't really change the whole situation.  If you want
to continue the discussion on the basic approach, please do continue
that on the original thread so that we don't lose the context.  I'm
gonna nack the respective patches so that they don't get picked up by
accident for now.

Thanks.
